RIA has an uncanny ability to get 95% of the things right that 95% of potential purchasers want.
I bought an RIA Tactical, and I am essentially happy with it. It was my first 1911 and might be my last. It is a "fighting pistol" if there is such a thing in the civilian market. It seems to function perfectly, is relatively accurate, and has a lot of premium features for a steal of a price. What's not to like....
Well...that last 5% or so of quality is what is missing. There were quite a few sharp edges in serious need of dehorning. The internals were parkerized, which while good for corrosion, are pretty bad for smoothness. The parkerizing seems a bit thin, and of course isn't that pretty to look at. This just might not be good enough any more, now that other manufacturers such as American Classic offer dramatically better finishing for roughly the same price. For perspective, my $169 CZ82 milsurp special is light years ahead of it in fit 'n finish, build quality, etc.
I am having an absolute blast shooting mine and tinkering with all sorts of upgrades. I don't think I have had more fun with a single pistol before. Having a 1911 is almost a hobby in itself, and RIA gets you admission at a price low enough to allow you to keep tinkering.
Can you go wrong with an RIA? Probably not. You just need to know what you are getting for the price, and be happy with the tradeoffs--I sure am. But as its price climbs, and competition gets stiffer, there may be better choices.
