Things like the SA "GI" are cosmetic reproductions of older models only, to feed the retro fad and the demand for a cheaper base model. Inside, where it counts, the ersatz materials and design mutations are the same.
The SA "GI" for example, has the key lock ILS mainspring housing with short stiff mainspring, funny mainspring cap, and no cap pin, just a retainer in a baggie you can stick in to disassemble the gun that far. It has a titanium firing pin and stiff firing pin spring to pass the California drop test. It has a flock of MIM small parts; although quality on those is better than it was. The two guns of my MixMaster project are pretty reasonable inside and I will be shooting one set in competition. The 7-round magazines that came with the .45 LW for the MixMaster Project are cheap and tinny. One would not drop free and was at spring temper and could be reshaped only with difficulty.
For a gun to actually carry and shoot, I'd get (assuming a SA in the first place) a Loaded and buy Metalform magazines and original style recoil spring guide and plug for it. I'd have a single sided safety put on if it came with ambidextrous. (Are you lefthanded?) That way I'd have conventional mechanics, at least as close as you can get these days, but with better sights and a beavertail, which I like for comfort.
I read good reports of the RIAs out of the Philippines, but my gunsmith says they do not look very nice inside. They are cheap and do seem to shoot, though.
