It functions..
My biggest gripe is that the pin isnt straight, has rough cast finish and is .151 inches when every other is .154 so this made the grip safety to frame fit sloppy and not as aesthetically pleasing as I was hoping.
Going Back
I thought this would be a fairly simple upgrade to my Colt but didn't happen as the stud was too big and would not go into the frame. I guess I could have spent who knows how long sanding the stud until it fit in but just using sand paper made me question how I could keep the shaft perfectly round without any flat spots or other irregularities. It's a safety-I want it to work right all the time. Going back to Brownell's and maybe I'll try another brand. It does look like a quality piece though.
Poorly manufactured, will not fit flush
I took this to a gunsmith who (prior to begining to fit it) informed me it would cost me too much in shop time for him to fit it because the thumb stud is too big. He was right. I couldn't get it in - I turned it with sandpaper and took off a few thousandths. I could get it in then and went about fitting the safety. Once it was fitted (didn't take that much) I noted it would not sit flush with the frame. Short story is it took me hours with several small files before I realized the reason it won't fit flush is because the base of the thumb stud isn't flush - it's oversized without a defined shoulder on it, possibly from molding? So no matter how much I turned the stud itself the base was sloppily manufactured and would never fit like a factory safety. I worked away on it for a while trying to get a 90 degree all the way around the base. I got it down to within a few thousandths of an inch of daylight, but still not completely flush with the frame. I would NOT put this safety on a custom gun. I do like the looks of it though.
Some parts like pins are hard to fit
It looks good but it isn't a drop in for any gun that is not used where the hole is loose. This unit is tight. It should have been noted that it is tight and then have an option to get one that works better on newer guns. I have used this on Mil Spec guns only do not know if they work on other custom guns. You know Colt is till the gold standard they are completely mil-spec. I have had problem with other parts like the main spring housing frame pin hole not cut correctly. Parts that have tight pins are harder to fit if you don't want to alter your frame.
not a drop in part
both pin & stud requires extensive work to fit properly
DON'T BOTHER
I should have read the reviews on the other listings. I never bought a bad part with the Wilson name on it until now. Too much work to fit the rough casting .I definitely would not recommend this part.
Poorly cast... required massive work
This is the first Wilson Combat piece I've ever been truly disappointed by. First the pin which holds this in place (through the grip safety) was massively out of round and very oversized at the tip. This required hand polishing that took the better part of two hours to get this to fit the frame. Then, I noticed it was poorly cast, with a metal seam running through the channel that the thumb lever and sear block meet... required a bunch of work with jewelers files to remove the metal seam and make the piece round enough to function in the frame. I've used these before and had no issues getting them fit. I've only ever had to do minor fitting to get the sear engagement correct. This particular one has no finish left anywhere on the "invisible" portions... it's nicely blued on the exterior, but the entire working surface inside required extensive work. Almost enough to turn me off on Wilsons thumb safetys... I'll probably try a different brand next build.
Not for a 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 pistol. It may work fine for other guns.
