I made an interesting observation today about my G-19s and how I shoot them. I have 2, a gen 2 model I've had since 1989, and a gen 3 I picked up a couple years ago. Both have 5 lb. connectors, tritium sights and Wolff recoil springs with stainless steel guide rods. I can shoot both of these weapons pretty well in that my groups are pretty tight. However, when slow firing, I tend to shoot both guns to left of center, using a 2 handed grip, thumbs forward. Even off a soft rest, the groups are slightly left. The interesting part is that as I increase my rate of fire to about 2 rounds per sec, which is about as fast as I can reacquire the front site and fire again, my groups are not substantially larger, but they are more centered, and perhaps just a hair to the right. So, effectively, I can shoot these guns fast more accurately than I can slowly. I've read other people ask "is it me, or the gun"? That's not the pertinent question here. It's me. There is nothing wrong with these guns. Would anyone care to speculate what I'm doing differently. I cannot point to anything specific, so whatever the difference, it must be pretty subtle. Any instructers out there care to take a crack at this? Oh, and it may be relevent or not, but often the web of my strong hand will get scraped by the underside of the slide during recoil in my normal, comfortable grip. Thanks for your feedback.
