Hey everyone, I’m a bit frustrated and slightly embarrassed by my struggles with changing the rear sight on my PDP. I quickly tired of the white dot sights that came on the pistol and ordered a set of Ameriglo Trooper sights for the PDP (bright orange front and blacked out rear tritium dots). I’ve changed quite a few Glock sights, but this is my first PDP. The rear dovetail seemed very tight - I could only insert the sight about 1/4 of the way by hand, while most reference I’ve found say they should fit 1/3 to 1/2 of the way in. I filed down the bottom of the sight a bit, which helped, but they still seemed pretty tight. I tried using a Wheeler Armorer’s Sight Tool, and after making some progress, it got very tight, and the small set screw in the Wheeler crank handle sheered off. I’m not impressed with that tool at all, despite the recommendations I’ve seen here. My MGW Glock sight tool has a steel handle that fits through a hole in the threaded shaft, which is much stronger. Anyway, I tried a brass punch, which moved the sight about 3/4 in, and then it got very firmly stuck and started mushrooming and bending the brass punch. I’ve never seen a dovetail this tight. Is this normal for a PDP, or could it be that the Ameriglo sight is out of spec? I think I’m going to have to take this to a “professional” to have this sight removed before I damage the slide. I considered stripping the slide and heating it up, but figured I better take a pause with this one. On a related note, I’ve read in various places that Glock sights work with the PDP, and then others say that you should only use PDP-specific sights. I’m curious what this group’s experience is. Thanks! |

Thanks for the reply. Do you have this MGW PDP-specific sight tool? Walther PDP Sight Pusher I really like the Glock version. It’s smooth and much more solidly built than the Wheeler tool. I’d love to find the Walther version, but unfortunately, it looks like it was discontinued years ago and doesn’t seem to be available anywhere. |
I think I put some suppressor-height Truglo night sights for a Glock in my PDP. That rear dovetail was pretty tight. I have a knock-off of the Wheeler pusher and it struggled to get the rear sight centered. The only thing I’ve found worse was the rear sight on my Glock 19X, which it couldn’t even budge. I’ve done probably a dozen sight changes at this point, so it’s been a learning experience.

I've been wanting one of the more versatile MGW tools for a long time, so this situation finally prompted me to get one. I found a good deal on a lightly used MGW Range Master and also ordered the MGW PDP shoe plate. Unfortunately, the rear sight is firmly stuck on my slide and won't budge with the tool. I think I may resort to using a steel punch to remove the sight and just consider it a loss. The brass punches are just bending when I try to tap it out. It's either out of spec for the PDP dovetail, or it needs to some significant filing to fit correctly. I've never had this much of an issue with Ameriglo sights, so it's a bit surprising. I may order a set of Glock Agent sights and see how well they fit in the PDP dovetail. I like the U-shaped rear notch on the Agent sights and have them on most of my Glocks. |
