Question: Will it fit a 1911 ATI?
Document: This is a perfect addition to my RIA 1911. A mediocre handgun, through replacing parts with Wilson Combat parts, has become a pretty sweet and reliable 1911. I highly recommend Wilson Combat Parts, as well as this trigger. The fit and finish look great!
I bought this from Rock Mountain Tactical Through Amazon to use in a S&W Performance Center 1911 that had a very sloppy fit. Usually these need to be fitted but this one dropped right in and cured my problem. It is a bit over priced but I had an Amazon gift certificate so it was worth it to me. Check out Roseco 69 on EBay $32.95 shipped was the best deal I could find.
I purchased this without ever completely disassembling my Springfied 1911 gvt before. I had to use a soft sanding wheel on my Dremel on all four sides to get it to fit properly, it worked faster than emory cloth. I am not a gunsmith, and had to watch the YouTube video (from wilson arms) to help guide me on where, and how the parts go toghether. I'd say, if you're patient, semi-mechanical, and have a few tools, you can do it yourself.
It came very quickly, I had to fit it to my gun but that is to be expected out of a drop in part. It has served me very well.
Another excellent Wilson Combat product. Excellent fit and finish. Have this on three of my 1911's and love every one of them.
Bought this trigger for my Ruger 1911. Excellent upgrade. Now the pistol feels and shoots like a high end 1911.
The coating is ugly. The gray finish coat is gonna have to come off anyway to fit this part. I suggest sandpaper, I also suggest removing all of the finish.Once in the frame, you will notice that it has a lower section on the back that only raises up on the sides for the grip safety.
Great product! Got here fast and dropped right into my rock island armory 1911 gov model. verry smoothe. It has a screw inside that you can adjust the length of trigger pull. The more you screw it in, the less pull.
The trouble came when I tried to reassemble everything..I had leftover parts. OOOOPS! Eventually I looked up the 1911 schematic on Brownells, and figured out where I went wrong. Great learning experience.Planning to do some more upgrades soon: extended beaver tail, extended slide catch, hammer upgrade, and speed chute mag well.
This was perfect drop in trigger upgrade for my Remingtong R1.Has a longer length to it, which feels fantastic. Much nicer feel than the stock trigger.The adjustable screw lets you fine tune it to your liking, and it the package comes with the right sized allen tool.Even though it was a drop in trigger, taking down your 1911 to the frame is not an easy task. It was my first time taking apart my 1911, and overall the job took me about two hours.
