One of the members at 10mmTalk had the frame break within 30 rounds of factory ammo. He had the damnest time dealing with EAA(one individual inparticular) for replacement pistol. He finally did get the replacement the other day, but they offered him some extra stuff for is troubles but they didn't provide them yet.

Some have had great luck with theirs, I have been skeptical and never purchased one but looked very hard at them.
