Mine has become a favorite, and is loaded next to the bed right now!
It came with two mags, both with the cast, larger base. I have since bought two mags from CDNN-they both have the stamped plate, and the indents on the bottom/sides. Those indents prevent the cartridge rattle present in the other mags, by the way.
While I only tried 6 rounds of Wolf "coneheads" that I had laying in the gun box, accuracy seemed okay, but my 82 jammed feeding one of the 6 on the way into the chamber, as if the rim didn't want to go under the extractor.
Accuracy at 25 yards with S&B and Fiocchi fmj was outstanding, as it was with Hornady and Silver Bear JHP's.
I have a slight amount of side-to-side play in the trigger guard, but certainly no hint of the guard moving downward while firing--that is something I would look at very closely.
My mag release is very stiff to operate on the right (left-handed) side. The left (right-handed) side requires a firm push, and I have to shift my hand to use it, due to the molding of the thumb-shelf on the grips. Not a problem with a 12 round mag.
