Hello, I've been reading posts on this forum since I found it last Sept. The info I learned here helped convince me to get rid of an unreliable CZ-RAMI. I bought an MP-40c November 2. I have only put about 100 rounds through it yet. No functioning problems. It seams to hit a little low. 165 Grain Hollow points. I have carried a Model 66 S&W revolver for several years. Great gun. Don't know why I ever bought the CZ. (yes I do, they weren't making the new MP at the time). Thanks to all for the great information here.
