Thanks very much for the encouragement and tips. I did get some additional tips about my habits and mannerisms on the line from an experienced shooter at the range today, hopefully following those tips will also help pull my score up.
It's interesting what you said, 10-96, about shooting with a fouled barrel. On the first round today (slow fire 50 yards), the shooter next to me mistakenly put 2 shots on my target. I shot that round again after the 3rd slow fire round and did a few points better. Whether or not it was the fouling in the barrel, I'm not sure, but it might have helped. I felt more comfortable after that first round of ten, today was the first time I've ever shot the pistol at a distance greater than 15 yards.
