You pretty much called it. FTFeed first time out. 50rnd box pf PMC FMJ. May have had 1 successful magazine but most were back to back FTF rounds.
Ramp on frame does not match angle of barrel ramp & frame ramp also sits higher. I blended them together with a 1/2 round jewelers file but haven't been back to range. 1st range session was Yesterday, Sunday. Also the take down was really difficult. There was a lump of metal from where the tooling machined a circular cut & left the lumo on the center of milling bit. Sanded that on a flat surface & kept the angle the came. MUCH easier to take apart now.
Pistol also shoot really low. 10-12yds I need to have the front sight way up. I mean flat sides of the tip of front barrel at the top of rear sights. Now with that hold I am aiming at the Top of an 8in paper plate & still hitting on the lower half of plate.
Any variations in rear sights? They look like my CZ 75B but I haven't measured.
