well i got the new cyl's and put the 22lr in and to me everything matched up perfect. loaded it up with the same ammo and same 15 yard target. It was like shooting a different gun. i put 8 rounds in a 2inch circle, first 4 i hit about 3inches high but all them hit in same spot and two over marked each other then i moved my sight a tad and found the bullseye. i put the cyl that came with the pistol back in and shot it 6 times and i went back to a 8inch group so im pretty sure that cyl has some kind of issue. thanks for all the reply's.
