Rock Island...sweet!
I just got a Rock Island, and it gets a big thumbs up.
I have no basis for comparison with other brands, just actual GI weapons from when I was in the Army many years ago.
I took the Rock Island to the range, and it ran great. The one failure was with the "Fisher-Price" factory 8-round mag....yeah, you need to get good mags for it.
It shot to point of aim at 7 yards, and shot where I pointed it. I felt like a gunslinger...trigger was between 4 and 5 lbs out of the box.
The parkerizing is nearly black, and seems different to me than the GI park, but perhaps it fades. Guess I'll find out in 50 years...
I don't like the factory grips, and have a set of fake ivory ones coming.
It's not a straight GI gun, but the changes are generally good:
-Straight 1911-style mainspring housing, not the -A1 curved type: I don't know if this is good or not. I'll have to do some more shooting, and maybe swap them out.
-Slight bevel to the mag well...a good feature.
-Ejection port cut...another good feature.
-Safety is slightly different than GI, but seems to work the same.
Other than that, basically indistinguishable from a GI 1911A1. I'm sure there are manufacturing shortcuts, but you get what you pay for, I suppose.
If you're looking for a no-nonsense out-of-the-box shooter, this is a fantastic gun and a good value.
