I always wanted a 1911 so I thought I'd give this pistol a shot. It's reliable, never had a FTF, FTE or a malfunction of any kind ( I put 1000 rounds through it). I've read that 1911's don't like hollow points but I put a hundred Remington 230gr hollow points through it without a hiccup. It's a solidly constructed and good looking pistol. Mine had a hairline crack in the rear sights but RIA replaced it under the warranty no problem. It's not that accurate, I get much tighter groups out of my FN FNS45 and my Springfield XD45. The parkerizing wears off easily just from normal holster use. If you really want a 1911 you can't beat this pistol for the price, but, in my opinion, there are much better modern pistol designs out there for the same price (more accurate, lighter, higher magazine capacity, better sights etc)

update, went out to the range today with my RIA 1911 .45ACP. was excellent right out of the box, accurate and NO issues at all. trigger pull was great, but will be changing sights soon! to TRUGLO TFOs...BLUF you can buy the expensive1911s if you have that kind of money, but I would put this gun up against any if them. shot about 200+ rounds of Winchester WB, Tul Ammo, and federal no hiccups at all, highly recommend this gun!

The sights are wretched.
I have contacted the manufacturer; but they provided NO DETAILED TECHNICAL SPECIFICATIONS to replace the sights.
I can find NO TECH SPECS to help order replacement sights.
It will cost me more than the gun is worth to send this weapon to the Novak people (who could replace the sights properly.)

Love this M1911! Rock Island Armory lives up to it's rep. Even came with two different grips, black rubber and wood, also has a very nice trigger squeeze. I'm also very satisfied with Bud's Gun Shop's service, website is terrific!
