Clerke revolver by Technicorp

I suppose If you have come across this post its because one of these guns came into your possession .

They are a neat little gun and are shiny as can be . 

The Clerke pistols are interesting pieces in history , being one of the first Saturday Night Specials . 

It was manufactured in response to a portion of the Gun control act of 1968 known as the "sporting purposes" standard for imported firearms. For the most part they made a list of features , calibers and other things they didn't like .

Now don't get me wrong there some good things GCA of 1968 did but most are pretty bogus and should have been beyond government control .

Moving on...........

 The check list prevented small ,low cost and concealable pistols that were being imported to no longer be available   . For the most part Domestic gun manufactures were pleased as the public pretty much had to buy what they were selling "normally at much higher prices "  .

With the void created my the GCA of 1968 new manufactures seen opportunity and started making firearms to fill the void . 

There Is loads of info out there about many of the Manufactures of Saturday Night Special pistols and the  Ring Of Fire pistols as well out their .

Sadly there really isn't a  whole lot on   Clerke Technicorp in one place "guess I'm trying to change that " .

So here Is the Basic info I can find .

Clerke Technicorp

Santa Monica, CA (1971)

Company later relocated to florida

Revolvers:

Revolvers seem to be considered Possibly the Worst revolver ever 

Caliber seem to be .32 S&W and .22LR 

Capacity 5 rounds of .32 S&W 6 rounds .22LR

Semi auto Pistols:

Calibers .22LR and .380 ACP

That"s all I know 

Rifles

They exist And some seem to go for a pretty penny and were available in various common calibers .

They were mentioned in a article From the New York Times June,20,1975 Main bit of info Here is that they sold for less than $20 dollars when new. http://www.nytimes.com/1975/06/20

Apparently Serial Number 1 was a gold plated gift to the plant Manager

Upgrading the trigger on your Century Arms C308 is pretty simple it just takes money .

http://www.triggerwork.net/hk9xrifles.html $65 - $70
Bill springfield does a impressive job reworking Cetme and G3/HK91 trigger groups and for a good price .

CETME - Trigger creep reduced up to 94%+, rough feel is smoothed out, pull weight reduced 50 to 60% from the factory 10 to 12 lbs pull. Sear bar is unitized to the trigger to eliminate trigger slop $65, option to reduce trigger over travel add $4. The complete pistol grip is needed.


http://www.williamstriggers.com/page3.html $80 +
Williams triggers list there trigger pull weight at 4-5# and if you have a HK91 trigger assembly and safety lever you want to use there trigger work on them is a bit cheaper .


https://www.hkparts.net/shop/pc/viewPrd.asp?idproduct=17014&idcategory=107 $169.95 +

PTR, HK91 - .308 Enhanced Trigger Pack - Match

Each trigger pack has been customized by the famed & renowned HK trigger smith, Bill Springfield. Trigger slack take up is eliminated and over travel is reduced. Pull weight averages 5-6 lbs, trigger creep is greatly reduced to a very short, smooth, crisp hammer release. 

Note: you will need a G3/hk91 safety lever to go with this pack .
