Just purchased my first handgun after month of firing off many platforms i decided on the PPQ. FIRST EDITION just appeared NIB at LGS. I POUNCED! i knew all there was to know about ppq,so i thought. Never expecting to find a first edition i failed to note tjw sifht issue on forum. I didnt notice a sight prob nor did my brother or dealer and maybe i am getting lucky. Long story short i need a holster for it and am unsure of compatibility w normal model ppqs?
