I've got one, the model M6000. I have mixed feelings about this weapon. On the one hand, it has features that are extra on most .45 acp pistols; skeletonized trigger, excellent grips, two tone finish, and beavertail to protect your hand. On the other it throws the brass about 20 feet behind and to the right. Not predictably, it changes throw pattern. It's not real accurate, although in fairness that may be me not the gun. Rear sights are only adjustable with a drift pin. Front sights non-adjustable. All in all, I'd say I'm pleased with it, but there's room for improvment. You almost can't beat the price, though. And it does take standard mags. Some might need minor Dremel work, but most will work. I've fed mine a steady diet of 230 gr FMJ, both factory and my reloads. Outside of the occasional brass mangling, no problems.
