I took my recently acquired M19 4", to the range for the first time today. The first string was supposed to be 25 rounds, but one cartridge had a bad crimp and would not chamber. I load 5 rounds at a time. The second string of 25 also had one round that would not chamber. Same issue, bad crimp, bulge in case. I shoot in what I would call a modified weaver stance. My right foot is back slightly with my shoulders square with the target. I am right-handed but left eye dominate. I shoot with both eyes open. My left arm is straight out, and my right arm is slightly bent. All target shooting was at 7 yards. 1911 target thrown in for comparison.
