I am by no means an expert,
BUT I have read and I have seen that the weakest link in a 1911 is the magazine. Rock Island gives you a hook-up with their products, they dont ship them with coarse parkerized GI style mags, You get that pistol with a hard blued Novak magazine, the follower is solid stainless and will not tilt, also its an 8 shot vice 7 with a heavy duty bottom pad. RIA 1911's are not as tight as a Les Bauer, they dont have all the bells and whistles of a Kimber or Para, However, it gobbles down Plated SWC's, gaping Hollowpoints, you name it. It is as reliable as my revolvers, and that i feel is truly saying something. Its a perfect fun gun, great to start out with, and even at that i would not feel the least bit disadvantaged using it to protect my life. NOW in my humble opinion, from there I'd like to move up to a springer' 1911. I feel SA puts out the next notch up in 1911, but then Dave29461's Taurus is a reasonable gun for someone who wants ambi safety's, rails, and all the modern doo-daddery.
Really in a nutshell, whatever inexpensive 1911 you buy, DONT BUY CHEAP MAGAZINES!!!! Buy Novaks, Chip McC, and the like.
