1972 cz70 Jamming
« on: March 17, 2020, 08:29:28 AM »
just got a 1972 cz70 and I think it is a really cool gun so far. I chose it because it was small, but had a hammer and was made of steel. So many automatics I see have a lot of plastic on them and I do not like that. I really like the history of the CZ70, I think the gun chose me.

One problem I am having, and I believe other people are as well, is the jamming. I cleaned and oiled the whole gun, and after about 4 shots in I got one round jammed in the chamber at a crazy angle. Appears to me to be a feeding issue from the clip? I ordered a couple new mags for it hopefully will solve the problem. any experienced users got tips for dealing with this problem in cz50/70? I have heard about mags being the problem online, but wonder if I am missing anything else. also just for extra info I am using the magtech .32 acp full metal jacket, which I have read is a good ammo for the CZ70.

I love this gun and want it to be fully functional. Cant be out here like a dumbass getting jammed up after 4 shots.  >:( ;D

Cheers,
SPD

Try a box of European ammo like Sellier and Bellot or Fiocchi. While .32 ACP (American) and 7.65 mm (Euro)
are interchangable, they are not identical.  Euro ammo is loaded to higher pressures.  The CZ 70 was never intended as an export model, so it was designed to run on Euro ammo. 
I had problems with my CZ 70 until I made the switch: after that I never had any problems.

Sure, hope it helps.  My only experience is with round nose bullets. If your hollow points have a different shape that could affect feeding.

Typical rimlock issue. The 32 ACP is a semi-rimmed round and if the total length of the round is too short, the rim of the top round can get caught behind the rim of the round below it. Find some longer rounds and use them.
