I have owned several 45acp handguns, this Rock Island is the best, With little sight adjustment I am getting good groupings at 25 yards. I am hitting 8" steel at 50 Yards. I've shot it three times so far put 250 rounds through it and have had a few failure to feeds, most likely my fault I should have cleaned and oiled the gun out of the box, it came in a sealed bag very oiled, I wiped it down and figured it was oiled enough. The other Issue I have is also with me, I can't reach the mag release with my right thumb without manipulating the gun in my hand,again that is on me. Buds was awesome to work with as always, the price was good (just wish online could get the cash price or don't show the cash price to the online customers). Overall I give the Rock Island Rock Ultra MS 45acp 5 stars (the issues I had with it were on me not the gun. Buds also gets 5 stars, they make the whole purchase process smooth and fast. Thanks Buds

It took a month to get the firearm after ordering it. Bud's and my FFL did their jobs, but getting the paperwork handled seem to take forever. I put 100 rounds of factory ammo through the pistol the first time out and it ran flawlessly with brass and aluminum cases. The gun feels solid, it has a nice beaver tail and the fiber optic front sight is a blessing for my old eyes. The G-10 grips are nice and the parkerized finish looks good. The only thing I might do is change out the ambidextrous thumb safety, but really it didn't get in the way at all. The thumb safety is solid. All in all, a really well made 1911.

Great buy for the money, shoots and functioned with no issues. Trigger was crisp. Only thing I didn't like was it had MIM trigger parts, which I replaced with aftermarket parts. The sights were nice, but prefer a "U" notch rear sight, so I replaced the rear with a "U" notch sight, Rock Island has their own dovetail cut, so I used a Novak cut rear sight and file fitted it to fit. I do a lot of shooting and the MIM parts commonly fail after awhile for the amount of shooting I do. Overall, a great buy for the money.

Great service from Bud"s. I bought pistol because of all the extras for the price. I have 150 rounds through it with zero malfunctions.The sights are adjustable which is a plus. The only dislike would be the parkerized finish. That said, the pistol is a very good value for the price, you can spend a lot more and get less.I may just get the slide ceracoated, because I like the gun.

This 1911 is awesome. Shoot like a dream. Have put around 1200 rounds through it ,with no problems. Break down is a little different and can be a pain at first. But overall great gun.
