Cz52
Dear Shooter:
No, no glue or loctite - there is something wrong for it to do that.
The CZ52 is one tough gun - the 7.62X25 cartridge it shoots is mean and penetrates many body armour vests!
Get a breakdown from the net, or gun parts.com and see if it's assembled properly.
Start from there, you have an excellent pistol - do not dry-fire - they are subject to pin breakage when dry-fired - never do it
One of the great dangerous mistakes I ever made was with a CZ52 I got from from my grandson - which I carried for a month after just shooting it to verify hit - he had been snapping it and when I went to fire it later (not in a serious context) it just "snapped". Embarrased, feeling like the fool I was, with a little panic, I quickly carried my 45 - I was a fool!
A good learning experience - I litterally had cold chills up my back - you guys know the feeling?
