Thanks. I think it helps that my hands are pretty strong/accurate from playing guitar/bass for so long. In fact with bass my R index finger is used to plucking which is a similar motion to pulling the trigger. A little bit of shake still, and I had to get used to focusing on the rear sight and let the target go fuzzy as opposed to focusing on the front sight. The other advantage is I used a stance that is very close to a standard "left front" stance in martial arts, so I had a very comfortable and stable platform.
Now the question is 9mm v. 40SW v. .45ACP. Not like that has ever been discussed before
