PT99/101 replacement rear sight FOUND!!! (installed w/pics)
As the title states, I bit the bullet and ordered a sight off of Amazon that looked like it might work, as I had a spare beat up PT99 slide that I use just for trying new things.Attachment 441177Attachment 441179
The sight is a unit from Kensight for a Colt revolvers and Gold Cup 1911's. Part number is 860-303. I bought it on Amazon for around $60.
Install was fairly straightforward. It did require minor modifications, but it was easy enough that I did it with hand tools, even though I have a drill press, mini mill, lathe, ect at my shop. I think my total time was about an hour, and that included cigarette breaks and reinstalling the firing pin, drop safety, extractor, ect.
Only two things are required for the install:
1) tapping the factory sight screw hole to M3x0.5
2) Drilling new holes for the front cross-pin, either in the sight or in the slide. I opted for drilling the slide, simply because it's a softer material than the sight.
I also used a file to open up the back of the sight blade channel just a tad for some clearance. It fit without it, but 2 minutes with a jeweler's file opened up the clearance to about that of a piece of paper.
I also opted to drill the front sight out, notch it, and install a fiberglass rod in it, and I used a piece of drill rod for the sight cross pin and peened it in place with an automatic punch, instead of using a roll pin.
Overall, I'm pretty happy with it, and will probably do the same thing to one of my nicer slides. My plan for that is to epoxy a piece of mild steel rod into the original cross pin hole in the sight, and then drill a new hole in the sight itself instead of drilling the slide. I'm also going to contact the manufacturer to see about them possibly producing a sight specifically for our guns, since it would be a fairly simple thing for them to do... SO PLEASE, IF YOURE INTERESTED, COMMEND AND LET ME KNOW! I can send them a link to this thread, and if they see enough interest, it will increase the chances of them doing it.
