Eight Strange Things I Sold at Radio Shack In 1980

July 1, 1980, just after high school graduation, I started working at Radio Shack.  On the occasion of Radio Shack's bankruptcy, I've updated this post in which I review the 1980 Radio Shack catalog found at Radio Shack Catalogs, I've found eight strange things that I sold in 1980.  Enjoy and comment with YOUR Radio Shack memories!!!

Eight Strange Things I Sold at Radio Shack in 1980


# 8 - A Lie Detector Kit

Yes, break out the soldering iron, wire this together, and measure the galvanic response of your friends!  When properly assembled, this kit would produce a screech that varied in pitch as your skin moisture changed.

I shudder to think how many killers were set free because of cold solder joints in this kit.


#7 - Record Player Needles

For those of you who remember record players (the dim little siblings of "turntables", usually distinguished by an internal amp and speaker), maybe you remember the needles.  Well, we had needles of all sizes and colors.

I drank the Koolaid big time... Radio Shack said we should only sell an EXACT match... don't sell an Astatic R-3a if their needle says R-3b, etc.  The frequency response could be wrong!  A laminated chart and a magnifying glass helped.

I was very frustrated that a coworker needed only seconds to sell a needle, while it would take me minutes.  And sometimes I couldn't find a match, while he always could.

Later, I learned that he figured if it was close it would fit and if not, they weren't going to drive back to the mall to exchange it for $3.99.  But lots of them did...


#6 - Car Stereos

Plenty of them.  At every price.  Because many vehicles had no radio, and most had a mono AM radio.

"Some vehicles may require minor dashboard alterations" it said.  Heh.  Yep.

You can't imagine the frustration of the average hobbyist when the AM radio they removed had two black speaker wires and one red hot wire, but the new AM/FM 8 Track had four speaker wires, a red hot wire, a yellow hot wire, and a ground wire.

Much debate at time of purchase... should they go with the tried and true 8 track, or the up and coming cassette?  I wish I had told them to save their money, buy a harmonica, and wait for the iPod to come out.


#5 - Car Clocks

Few cars had clocks.  Finally, a clock you could install in your car!  I'm not sure if watches were rationed or what, but folks would gift these like crazy.  It was one of those things no one wanted but everyone knew someone else would want.

Three wires... one ground, one ignition, and one always on.  "My car clock resets to 12:00 every time I turn it on...".  Oh, and if you installed it properly, it still might kill your car battery.


#4 - Bike Radios

Once dad had a stereo in the car (and maybe a clock!), Junior wanted tunes for the road.  These actually worked, and you've gotta go an extra $9 for the horn.

Notice that the rider doesn't just ride, doesn't just listen, doesn't just whistle "Flight of the Bumble Bee", he or she also conducts the music with their right hand.  #notsafe


#3 - Noise Filters

I'll let Wikipedia explain.

You've made the slight dash modifications, check.  Matched and adapted all the wiring, check.  Turn the key to ACC and listen... IT WORKS!  I'VE GOT A RADIO IN MY CAR.  I am so happy.  I'm going back to buy that Car Clock I had my eye on.  Start the car and Bzzzzzzzzzbzzzzzzzzzzzzzzzzbzzzbzzzzzzzzzzzzz.

Time to choose from a bewildering array of noise suppressors.  How about one that installs on the center post of the distributor of your ignition system, what could possibly go wrong with that one?

I guess the voltage tester was appropriate, you could use it to figure out why the headlights always stayed on at the completion of your little project.



#2 - Crystals

No, not the New Age variety.  These were tuning crystals.  For your walkie-talkie, or your scanner.

For your scanner, we just needed to know the pin spacing and the intermediate frequency.  Then we'd refer to a typewritten sheet to see the local Volunteer Fire Department or Airport frequency, grab the correct crystal which would be the difference between the frequency on the sheet and your intermediate frequency, verify the pin spacing, and send you on your happy way.

"We don't sell crystals for a Midland scanner, it has a different IF than a Bearcat." 
"Do you have fire for the Bearcat?  Just give me that." 
"Yes, I do, but it won't work in a Midland." 
"It looks the same." 
"It does, but it's not." 
"Let me try it." 
"Crystals aren't returnable." 
"OK." 
Two hours pass. 
"My husband bought this earlier and they gave him the wrong one, I want a refund, it doesn't work in a Midland."

For your walkie-talkie, we'd ask what channel you wanted, select a native crystal of that frequency from a chart for transmit, subtract your intermediate frequency and select an offset receive crystal.

"Now remember.  This one is channel 17 transmit, this one is channel 17 receive.  I'll tape them to the receipt."

Of course the light printing would come off, the customer would confuse the crystals, and return with the off brand radio, a bag of unidentified crystals, and we'd have to figure it out.


#1 - Stereo Systems

So many.  So many varieties.  This was the "Big" system, and we sold it occasionally at full price, and very frequently when it would go on sale for $1,500 or so about twice per year.

What a setup.  Those speakers are about three to four feet high.  In the box, you could always fit one in the back seat and one in the trunk.

And the subliminal sell in the ad was that if you bought this, even if you looked like Matthew McConaughey in Dallas Buyers Club, a Marie Osmond lookalike would be there to listen to music with you.

Most of the stereo systems sold were in the $799 to $999 range.  But we sold plenty of "The Everything System", and I'm stunned today to see that $1,749 in 1980 dollars is $5,050 today.  Wow.

My Gangsta Glock - How I Got It, Lost It, and Got It Back


Sam's Gangsta Glock 26, with MNPD theft report

The Glock 26 #Glock26 was released in the US in 1994, and I was one of the first in line (shocker, I know).   I was thrilled to have a full power 9mm pistol in a compact package with Glock reliability.

The Glock 26 was a premier "Pocket Rocket", an unintended consequence of the 1994 Omnibus Crime Bill which banned the manufacture of magazines capable of holding more than ten rounds for civilian sale.

Glock and other manufacturers realized that if the magazine's couldn't hold more than ten rounds, the guns could be smaller!  And an entire category of centerfire, subcompact firearms with doublestack magazines, all scaled down from full size sidearms, became available.

I quickly became attached to my Glock 26, and it became my vehicle gun.  I kept it in a 35mm camera case, which did not seem out of place in 1994.

On July 12, 1996, I parked my truck at Sixth and Church in Nashville and returned to find a broken window and a missing camera case.  And a missing Glock 26.  I filed a police report with Metropolitan Nashville Police Department.  At the time of loss, the gun was loaded with eleven rounds of Corbon 124gr jacketed hollow points in a ten round magazine with a Pearce grip extension.

I bought a replacement Glock 26, and chocked my loss up to bad luck.

---

Four years later, I received a call from Officer Dave of MNPD.  It went something like this:

"Mr. Shallenberger, this is Officer Dave of MNPD and I think I have something that belongs to you"

"Is it a Glock 26?"

"Yes."

"Great!  How did you find it?"

"Someone killed ten people with it."

"OK, when can I get it back."

"Ha.  Just kidding about the ten people.  I'll check with the DA and we can probably release it soon."

When I picked it up, they wouldn't let me have the ammo.  The gun was clean, heavily over-oiled, and was returned with the original magazine.  They discarded seven rounds of Corbon 124gr jacketed hollow points.  I don't believe it was fired four times, rather, I believe it was loaded and unloaded frequently with an occasional lost round.

Officer Dave explained the recovery:

"We got a tip that a felon was in possession of a handgun, from his ex-girlfriend.  So when we spotted the guy at Mapco, we questioned him.  He did not have the gun.  We pulled the security film from the Mapco and saw him stash the gun in the potato chips.  We went back in and there it was, next to the Doritos.  So we booked him as a felon in possession."

Recently, I had Glock install metal night sights and replace every non-serialized part with new.  After twenty years of ownership, and sixteen years of possession, it remains my favorite.

Tiny Glocks - In Three Sizes

Here's a quick shot of (lower left to upper right) the new Glock 42 .380, Glock 26 9mm, and Glock 36 .45 ACP.  The Glock 26 is my "Gangsta Glock" with a  criminal record, I'll write about that soon.

Glock 42 UNOFFICIAL Armorer Update and Glock 26 Comparison

Glock 42 UNOFFICIAL Armorer Update and Glock 26 Comparison 

#Glock42 #Armorer #GSSF


A teardown and comparison, part by part, of the new Glock 42 .380 and a Glock 26 Gen 3, with specific assembly and disassembly tips.  Explanation of steps unchanged from prior models are not provided, only unique instructions are explained.

In The Box




The Glock 42 ships in the same box as the later Gen3 and all Gen4 Glock models.  Two six round magazines are included, along with a lock, manual packet, and a fired casing in dated envelope.  The Glock 42 does not ship with a magazine loader.  The Glock 42 six round .380 magazines are easy to load, requiring a loader even less than the 9mm models.

Field Stripping, Lubrication, and Reassembly


The Glock 42 field strips exactly as prior models.  Once field stripped, the components are the slide, the barrel, the recoil spring assembly, the frame, and the magazine.  Instructions are included in the factory Glock manual.  Glock does not recommend further disassembly by non-armorers.  Lubrication and reassembly are the same as prior models.

Slide Components - Firing Pin Assembly


Glock 42 top, Glock 26 bottom - Dimensions differ, geometry similar


Glock 42 top, Glock26 bottom


Glock 42 top, Glock 26 bottom - Firing pin spring and firing pin spring cups APPEAR to be common between these models

Extractor and Firing Pin Safety

Glock 42 top, Glock 26 bottom


Glock 42 top, Glock 26 bottom


Glock 42 top, Glock 26 bottom - larger, non-rotating firing pin safety, differs from all prior models, installs only in one orientation due to shape of firing pin safety head


Glock 42 top, Glock 26 bottom - Springs APPEAR common between models


Glock 42 left, Glock 26 right - Firing pin safeties installed

Sights


Glock 42 top, Glock 26 bottom - Front sight screws APPEAR to be common between models, note that machining details (relief for screw head) has changed


Glock 42 left, Glock 26 right - Sights APPEAR to be common between models, note that Glock 42 does not have beveling at front edge of slide found on subcompact models


Glock 42 left, Glock 26 right - Glock 42 sight is narrower and appears to be lower.  Channel liner was not removed.


Glock 42 right, Glock 26 (Models 17 through 41 same excluding possible 18) lower left, armorer inspection cover upper left - The inspection cover used on all other models will not fit the Glock 42, either a unique orange armorer inspection cover will be needed or a spare Glock 42 cover can be cut down to inspect engagement.

Frame

Glock 42 has only two frame pins, the trigger pin and the trigger mechanism housing pin, similar to early 9mm models.  The trigger mechanism housing pin is removed first, left to right, and differs from prior models only in dimension.  The trigger pin is removed second, left to right, and differs both in dimension and in additional serrations on the left (slide stop lever side).  These serrations appear to serve to locate or secure the new slide stop lever design.


Glock 42 parts left, Glock 26 parts right - Note lack of locking block pin on Glock 42, significant change in design of slide stop lever and spring, change in slide lock spring detent.

The slide lock is removed by depressing it in the middle fully, then pressing it out with the armorer tool from the left side until it can be grasped and pulled out the right side of the frame while covering the slide lock spring to prevent its loss.  The slide lock spring is not captive.  To reassemble, seat the slide lock spring, depress it with the armorer tool, insert the slide lock from the right side so that it captures the spring and press it through to its normal position.  Remember that the barrel groove on the slide lock should be up and to the rear so that the part number is readable from the shooter's point of view.

Slide Stop Lever and Assembly/Disassembly Change



Detail of Glock 42 slide stop lever installed and trigger pin - Note differences in lever and pin, and additional grooves on trigger pin


Glock 42 top, Glock 26 bottom - On Glock 42, slide stop lever is removed after the locking block and installed before the locking block

Magazine Catch


Glock 42 right, Glock 26 left - Glock 42 magazine catch functions, removes, installs just like Gen4 Glock models and can be installed for right hand or left hand use.  Magazine catch spring was not removed but appears to be identical to part #280 used in other models.


Trigger and Related Components

Glock 42 left, Glock 26 stock center, Glock dash right


Glock 42 left, Glock 26 stock center, Glock dash right - Note similarity of angle between Glock 42 and standard weight Glock connector (center)

Important Reassembly Change

My 2012 Glock Armorer's Manual states "Reinstall the trigger bar and ensure the left arm of the cruciform goes on top of the drop safety ledge of the trigger mechanism housing" (page 54).  Most of us learned to do this by "rotating" the trigger bar into the housing, which is easier than normal when using a New York spring.

On the Glock 42, however, it is critical that the front edge of the cruciform be captured by the "hook" on the trigger spring.  If the cruciform is not captured by the hook, the trigger does not reset.  (Tested dry firing, assumed but not confirmed with live fire).

Apparent Trigger Options


Glock 42 trigger mechanism housing and trigger spring

The Glock 42 trigger spring can be installed with the foot of the spring in either of two different detents recessed into the trigger mechanism housing.  The illustration showing the trigger mechanism housing in blue, the trigger spring in green, and the hook of the trigger spring in red show that the two positions change the leverage of the spring as it aids the trigger bar moving back against the firing pin and spring under pressure from the trigger.  

I observed a lighter trigger pull with the trigger spring installed in the upper position and a heavier pull in the lower position.  I have not quantified the difference.  

Update 3/1/2014 - GSD17 on Glocktalk.com and others have caused me to rethink the second spot for the foot of the spring, and convinced me that the upper spot is a disassembly aid only.  

Magazines


I forgot to take one apart, but at a glance they appear to disassemble and reassemble like all prior.  The magazines have notches for left hand and right hand mag catches.

Summary

The Glock 42 components in general appear to be appropriately scaled down from larger models with only five exceptions

1 - Slide lock spring

Change from irregular leaf to coil, probably a cost savings and to aid ease of assembly, disassembly.

2 - Slide lock

Slight beveling of spring detent to accommodate disassembly procedure change necessary for coil spring.

3 - Slide stop lever

Change to spring, appears to make inadvertently misassemble more difficult.  Prior versions could be installed with the slide stop lever spring oriented incorrectly relative to the locking block pin, resulting in a slide stop lever that locked back after every round.  Change to spring requires that the slide stop lever be installed prior to the locking block.

4 - Firing pin safety

Larger and non-rotating.  Occupies the entire path of the nose of the trigger bar, perhaps so that position of trigger bar nose left to right is less critical and the locating bump found on later trigger bars is not required.

5 - Trigger Spring

A significant change to the spring and its assembly, providing multiple trigger pulls with no change in parts, only a change in reassembly orientation.


I expect to see all five changes in future revisions to existing Glock models.


Comments welcome and I'll credit significant revisions.

2/3/2014 - Added detail photo below of Spring Loaded Bearing to address Mike's comment.  Spring loaded bearing now appears to have a molding dimple on the slide cover end.  I've not noticed this in the past, the Glock 42 may or may not be the first with this change.
