I shot the PMXs for the first time today. I put 140rds of Geco 124gr FMJ and 50rds of Speer Lawman 147gr TMJ through it. The latter was with a TiRant 9 suppressor on it. It functioned 100% and the accuracy was really good. The bullets went right where I wanted them to go. It definitely needs a brace or a stock, but it did perform well as-is. The spent cases went a bit far for my liking, so I'd say that it's slightly undersprung. Ergonomically, my only complaint is that the safety on the right side of the pistol can get in the way depending on how you grip it. I'll see if there's a way to delete it. The action is smooth and the bolt locked back on every empty magazine. I'm definitely happy that I purchased it.
