Ok, guys...I'm a frequent reader but new poster here...love the forum..I have a Taurus 24/7 pro in .40, and an HK USP 45 compact I'm pickin up in a few weeks from layaway. Here's my question. In my left thumb, I have a steel pin, and some muscle added to the heel of my palm...My right thumb is nothing but cartilege..Soooo, two handed shooting is not bad. One handed, left, is very difficult, one handed right is almost impossible due to not being able to grip pistol tightly. Anyone know any tactical training schools and/or drills that I can do to improve my draw and my grip strength? Thanks for the input, everyone
