i have a FEG PA-63 and, for whatever reason, want to upgrage my sights. prior to the downfall of makarov.com, i picked up a sig rear sight, wich with a little work fits well and looks good. problem is, i have no idea how to proceed with the front sight. a PA-63 is a direct blowback design similar to a makarov, walther pp, colt 1903 pocket, the recoil spring is mounted around the barrel and acts directly on the front of the slide. i'm not sure if the metal there is thick enough for a dovetail. has anyone had any experience with a sight instal like this? i was thinking a millett dual crimp. or a 1911 style stake on. is it possble to add material to the top of the slide and dovetail that, or slot it revolver style? thoughts?
