A stamped on frame???

[leadhead2]

Hi Guys,
Can someone tell me what the "A" stamped on the rear
of the frame means?
Thanks for any info,
Denny

I think all of them have this mark. All of them that I have seen on the internet, to include mine, all have it. I am guessing it's a form of proof mark, or manuf. stamp. Sorry I can't help much more than this. If I find out anything more, I will reply.

I think I read somewhere it had something to do with a trigger upgrade or
something on that line.

GOT IT, well sort of... I wish I spoke Polish and this manual would make more sense. Google tranlator and I teamed up. This is what the manual says about it.

"... Lasted until 1977 production of the basic variant of P-64 in the number of 190 thousand.
units. Already in 1971, after a series of accidental launching-pads with the P-64 early
production, leading to changes in the structure and tap the trigger bus. Then changed
shape and angle of the tooth undercutting security, obniŜaj¹c point at which the hook
run the tap. Modified cock was determined from 1972 stamped on the
the left side of the letter "A". By contrast, in 1973 made further changes
trigger mechanism was changed and re-cock, giving his head shape
triangular."

obniŜaj¹c, as far as I can tell, means droopy/descending. So, it could mean bottom.

So, I cannot tell if the A is really talking about the trigger bar system and the sear... or if it's talking about the hammer. Hammer is translated in two different ways. It can be called the "cock" sometimes and "tap" other times.

Well, that's all I know about it I guess. Guess I'll keep researching and maybe I'll stumble upon a Polish-speaking person that can further enlighten me.

I have read that the sights were set at an "exaggerated 50 meters". This Polish manual claims it to be fixed at 25 meters...

"9 mm pistolet wz. 1964 is the personal arms, rifles, serves to combat for short distances (up to 50 m) and self-defense."

In the technical specs it claims...
"Firearm adjusted to: 25m"

And furthermore in the manual it states...
"Firearm- shall be regulated at a distance of 25 m. Placed and adjusted on a permanent basis."

So, it's effective UP TO 50 meters, but sighted and set for 25.

Also, the manual claims that the original projectile weight fired out of the gun is 6 grams. That would equal 92.6 grains. That's way different than the 71 grain figure that other manual claims that others have said is incorrect because a 71 grain bullet has never existed. Well, not any that are ball ammo. Total cartridge weight was 149.7 grains with powder and all.

Figured I'd share this random info... I do see that someone already recorded some of this in another thread.

the only change that I can tell , is the trigger return spring they went to a 3 turns of .32 dia. round wire instead off the 4 turns .28 dia. square wire and withe the triangular hammered guns they shorten the firing pin about 1\2 mm to 1 mm. and that's about it
