I'm not a muscle guy, I'm 5-9 155 and 65 years old ... I found that as time passed, I was having a hard time getting the sights back on target after firing some of the more popular SD rounds, especially +p ... So I got a hand-wrist exerciser, one of those things you squeeze over and over ... mine are from Prohands, but you can find similar gadgets in any sporting goods store ... I started with the medium tension and am now using the heavy tension; I usually do 10-15 minutes every day while watching TV ... the difference in my performance at the range is simply amazing. The additional strength in my hands and wrists has quickened my time getting the sights back on target, made absorbing recoil far easier and has increased my accuracy by at least a factor of 5. It's one of the simplest, most effective ways I've ever found to improve accuracy ... anybody else have a similar experience? I recommend it to all my shooting friends, and have had a number thank me for the suggestion.
