A new guy at the gun club tonight had a P99 (40 cal?) Before he finished Stage 1, his magazine came apart and dumped it's contents at his feet. After 2 more shots, the second one did as well. It looked like a rail holding the floor plate sheared off, allowing spring, cartridges, and mag parts to fall out, in both cases. Is this a common problem with Walthers? Wanna kill these ads? We can help!
