    PT99 Rear Sight Repair

    The elevation screw on my PT99 has broken. Looks like from other posts replacement rear sights are not available, so I'm going to try to repair the one I have by replacing the broken screw.

    Some questions:

    1 - Does anyone know the thread specs for the elevation screw?

    2 - The existing screw seems to be secured by a very thin pin that runs crosswise in front of the screw. It's less than 1/16" because I cannot get my 1/16" pin punch in the hole to remove it. Does anyone know the correct size punch to get the pin out?

    Thanks!

    I believe it is a 0.050 diameter for the pin.

    Don't give up the ship, if I recall correctly some one posted with in the last 6 months of a fix or source for the dreaded PT99 rear sight issues.

    I am certain that it was here on the TA Forum that I read this. I remember thinking that I need to come back and bookmark that post because one day I may need the information it held...…...and, yes, no I never did go back and bookmark the post.

    Doesn't look like any replacements are available, does anyone know what the thread specs are for the elevation screw? I couldn't match my broken one to anything at the local hardware store.

    It's looks like a 2mm.
    Mine is a captive machine screw so it doesn't come out of the sight. and the little .050 cross pin doesn't want to come out so I can measure the screw.
    I would suggest that you completely gut the slide and take it with you to a real hardware store and try testing screws to find one the fits properly.

    Well, getting nowhere so far...so let me ask another question:

    Has anyone thought about trying to mount a red dot sight on a PT99 since there appear to be no other sights that can be easily fit?

    I an sure you are aware that the rear sight assembly holds the extractor pin and the firing pin block in the slide. So no matter what you end up doing you will have to keep the remains of the rear sight on the slide.

    I believe I have seen, once, a scope mount for the PT99, but you will have better luck trying to bottle unicorn farts.

    Seriously, I had a PT 99 that the sight elevation screw would rotate a partial turn each time it was fired. I changed sights, I have another 99, but this did not fix the situation. I ended up replacing the slide, and using the original sight. Apparently, which I could not prove, the threads in the old slide were stripped. Finding a plug tap for the elevation screw, was another unicorn chase.

    Your quick fix, would be to change rear sights. GB often has parts guns, which isn't a bad thing with the Taurus parts situation the way it is.

    when shopping for a replacement sight on eBay, be sure you get one of the correct size. You might be able to find one originally made for a revolver. An alternative is to get a slide from a PT92.

    Tx to all who replied.

    jeeper1: I knew about the firing pin block but did not realize the rear sight actually held in the extractor pin.

    I may go back & try to drill/retap the elevation screw hole to something a little larger. Anyone ever try this?
