Fusion Trigger
Not a drop in on the ATI FX Military! More fitting than I hoped for and has a a considerable gap between frame and beavertail. Would recommend to a friend but would urge having a gunsmith install it.
Not a Drop-In Part
Although the end result was pleasing given that this is not a custom fitted/frame cut and blended part, dropped 2 stars for the false description. Drop-In this is definitely not. I am a Colt-trained armorer and this is not my first grip safety. Used a brand-new Colt 1991 Government Series 80, which you would rightfully believe to be the blueprinted standard of 1911s. While I expected to fit the safety nose to the trigger, the entire part gave me fits and needed filing, stoning, and rebluing in several areas in order to move freely with the thumb safety installed. Easily 2+ hours of work. The fit of the beavertail to frame tangs was the best aspect of the part - no issues there. The rest of it was a horror. Would have been 4 stars if I had been expecting the amount of work involved.
Needed Elbow Grease
Didn't quite drop in. The sides of the safety were grabbing the frame enough to stop it from functioning. Took about an hour of sanding the sides of the safety with 320 and 400 grit paper to make it fit and function properly Installed this on a Colt Delta Elite. Polished the sides after fitting and it now looks and feels great. Didn't need to file the trigger bar stop as seen on youtube or mentioned here. Trigger functioned perfectly after safety was fitted to frame.
not a drop in to a Colt Goldcup
This is a nice looking grip but it does not match my Gold cup. The beavertail extends way to far back and does not fit flush to the back of the frame. Otherwise it looks great and is well made.
Works fine but doesnt look too great,
I gave it 3 stars because it does do what it says. It dropped right in no problems or issues. I installed this on a nickel plated Rock Island Armory. It saves your hand from slide bite and allows you to ride your grip higher which makes my shots a bit more accurate. It just looks like garbage when installed. It sits a little off axis and has gaps in alot of places. It did polish up very nicely to match the nickel. It does work 100% though. If you care more for the function than the aesthetics its a go.
Wilson Combat
The grip safety dropped right in to my Colt XSE, but there is a sizable gap between the frame and the ears of the safety. I need to see how it shoots and maybe dehorn it a bit. There is enough of a gap and edge on the safety that I think I may cut myself while shooting it.
Drop-in...Not so much
WHile this is obviously a well made part I would not call it drop-in. In my 70S Commander it required what I would describe as extensive fitting. I had to file and polish virtually every surface that made contact with the frame. About the only place that didn't require fitting was the actual tang that contacts the trigger. I marked "would not recommend to a friend". One exception to that would be a friend with the skills to fit it.
Took a lot of fitting!
This is my second Wilson Combat Drop In Beavertail Safety. My first was for my Colt Defender and it took minimal fitting. This was for my full size 1991A1 and it took a substantial amount of work to get it to fit. This in turn took off large amounts of bluing. I am fortunate to have attended a 1911 armorer's class or it would not have been possible to fit. Once on and cold blued it looks good on the pistol. I wouldn't do it again.
Not Recommended for a Colt Gold Cup
I bought this product to install on a Colt Gold Cup Trophy MKIV/Series 80 model. Although I am a Colt factory trained armorer I was hoping this would be a drop in part. To my disappointment it was not. I suspect it could work with some minor fitting, but I don't like having to file if I can find a true drop in replacement. In my opinion there is too much room for error in doing so. I returned this item and am still on the hunt for a true drop in. I checked I would not recommend this to a friend, but to be specific I would not recommend it for a Colt Series 80. It may work fine for other guns. In reading the other review it appears the other gentleman had good luck with it in a Springfield. I carry mine as a defensive weapon and cannot afford for something to hang-up or catch.
