I have a Rami polymer in 40 S&W. It has a slight frame bulge, and I sent photos of it to CZ. They offered me nothing. I read comments like the one above, and I shot the crap out of it trying to get it to fail. But the bulge hasn't changed, and the gun shoot flawlessly. It hasn't had a failure in well over 700 rounds that I've put through it. I carry it daily with confidence, and any time I go to the range, it gets at least 50 rounds through it. I don't know if it has any special value, and it ain't for sale. I'm getting ready to do a trigger job on it now, and I can't wait to shoot it when I'm done.
