Looks good, I like the sights, I like the grips. Haven't had a chance to shoot it yet. I would have liked a spare magazine. I rack the slide 5-10 times a day to loosen it up a bit.

This rock island is solid and good quality for the price. Dont let anyone tell you RIA is cheap in execution, it has multiple SW parts, a few WC parts, and it came with a Chiappa 8rd mag with a really strong spring in it. Has some rough spots between the sear and slide (not 'shk shk' more 'cla-clickada-clack') but this will wear in with ...Read More Read more about review stating Dont believe the non-hype.

First time to the range, the FS in 40S&W was dead on target and gobbled up everything I put in it. Even coated lead bullets. And I was hitting 10" swinging targets off- hand at 40 yards. Worth every penny you pay for one. Purchased some extra Armscor mags, they were also completely reliable with no misfeeds, even feeding a brand new gun during...Read More Read more about review stating Very accurate and reliable 1911

I've heard about Rock Island 1911's quality even for a less expensive weapon. I heard correctly! From the first shot I knew I was in for a treat. It was such a pleasure to shoot. The recommended 500 round break-in was a dream. I had 3 failure to load with the supplied mag, the other magazines had no issues. I contacted Rock Island and they're corr...Read More Read more about review stating The 51448 is an Outstanding Pew!

Very nice pistol at a reasonable price. I have put 300 rounds through it without any issues. The matte black finish is functional, not pretty. The magazine well, fiber optic front sight, white dot adjustable rear sight, and grey VZ grips are nice, included upgrades from a standard model. The only criticism I have is that the grip safety on my pistol rattles just a little. I have another RIA 1911 that I purchase a year or two ago which didn't/doesn't exhibit this. I adjust the sping to put more tension on the safety and expect that to remedy the situation.

The Rock Island Ultra is a beautiful 1911. Ordered it an a PSA AR-15 on Thursday evening, shipped on Friday and at my FFL on Wednesday. Awesome service from PSA, as usual.
