Don't get discouraged.
I've found that my two hand shooting was hiding a lot of trigger press mistakes. I read that somewhere....either here or on a bullseye forum. I've started doing most of my dry fire practice one handed only and it's paying dividends at the live fire sessions.
In the past, one of my biggest mistakes was ambushing the trigger when the sights wobbled to a "just right" position. It took me a while to realize that a smooth, close to perfect trigger press is far more accurate than jerking the trigger ambushing it. I cringe at all the ammo I blasted away over the years ambushing the trigger.
I'm not seeing low and left hits like I used to....and I consider that progress. I credit that to dry fire and advice I've read on this and other forums.
Doing more body weight and dumbbell workouts too. I'm finding that the more of that I do, the easier it is to hold the sights steady and my arthritis seems to hurt less when triggering off .45 rounds with the G41. Trying to eat better....more water......more of all that jazz.
Regards.
