I bought this gun NIB last week and had a chance to shoot Saturday . Ammo used was Winchester FMJ and SJHP reloads. I used a total of 75 rounds (limited by ammo supply). First impression: nice looking gun with factory muzzle brake in barrel ports. Rough edges and machine marks in lots of places. Very tight (?too tight) slide to frame fit . Heavy ?18 lb recoil spring. I sighted-in the gun at 25 yards (had to raise the elevation considerably from how the gun was boxed) But, the groups were around 1-2 inches so I'm not complaining. Reliability was not good with numerous failures to eject . I'll admit that the gun needs to be "broken-in" more and I did use questionable SJHP ammo. Still, I think the spring may be too heavy or the slide to frame fit may be tight. I'll shoot a couple hundred more rounds and if it's still a problem, Springfield Armory is only 20 minutes from here. I'm optimistic about getting this gun to function. Hell, even my Kimber had problems.
