I've got a CZ-52 that I've had for a long time.
I've been slowly replacing parts on it and recently the Takedown latch/hold open pin keeps walking out due to recoil.
I'm wondering if I should replace the pin/takedown latch and spring... My hold open catch is also worn, might replace that too...
Anyone else have this problem?

I have replaced the firing pin, safety detent spring, roller cams and the barrel (old barrel was pitted from shooting a lot of Romanian corrosive ammo and being about 60 years old)... I kept the old barrel and test my ammo as I load it for fit - it works great!
