I just purchased the MGM Rear sight tool and am having difficulty getting it to work with my Glock 21. My Glock 23 and 35 are fine, but the slide of the G21 seems to big. It was advertised as working on all Glocks. Has anyone successfully used this tool on a G21 or G30?
I have used the MGW tool on a G21. Didn't have any problems. What is the issue you are dealing with?
It does not seem to fit. The slides for my G23 and G35 fit fine, but the slide for the G21 is a little bit to tall to fit. When I slide it on on the platform at the bottom, it hits the part at the top/
