Zero issues here. Depending on how far back in the threads you go, you can see a lot of Rami issue threads. Most can be attributed to 2 things. Fly byes and CZ newbies.
The fly byes come on with an issue, and get helpful advice. Guess what, they never post back. So we have no idea what or if any issue was ever solved, or if it even really existed.
The CZ newbies take the pistol straight to the range dripping in packing grease. Have issue right off the bat, come here to complain. They get told to give it a thorough cleaning and relube, and clean the mags out. Bingo, up and running full force.
FWIW, that's why on a lot of issue threads, the first thing someone says is to clean and relube, and clean the mags. CZ's like to run wet, don't need to be dripping tho
The next issue will usually be solved by making sure the trigger bar spring is riding in the trigger bar groove. These fixes go with all CZ's.
The only maybe issue with the Rami is the recoil spring. Most short barreled pistols have a shorter recoil spring life than their big brothers. The Rami can start having issues after about 500 rounds but I think a lot of that depends on the ammo Only the outer spring needs changed. $5, so buy a couple and save in shipping. I've got around 700 rounds with zero signs of weakness on mine. Just to be on the safe side I keep a new spring in the gun for carry. Use the older spring at range. YMMV
