New to the forum. Took my CZ 75B Omega Urban Grey out for the first time last weekend. I had spent time with it prior to shooting (got it over the winter) disassembling and reassembling to get accustomed to the ins and outs, etc. (This is my first 75, but I've got another couple of dozen pistols in the collection.) The pistol seems to be very well made and everything looked great.
Field stripped the pistol today to clean it and I immediately noticed these strange ridges/bumps on inside of the frame, like something had been banging around inside the gun while firing. The slide still glides like silk, so there doesn't appear to be any damage to the rails, etc. And while shooting it everything seemed to function just fine. (200 rounds unsuppressed, another 100 rounds suppressed.)
The dings were definitely not there before shooting it the first time. All I can think is that the short recoil rod was allowing the recoil spring to bounce around inside the frame? Nothing else seems to be damaged and everything functions fine otherwise.
Is this a known issue with CZs or is there something wrong with this pistol?
I'm sure photos would be helpful... I'll try to remember to snap some photos tomorrow.
