I do have a plr, and I hunt with .44 mags, .454 casull's, and a .270, all in handguns. I also like to carry a .44 mag snub nose that, while not a crack shot, you wouldn't want to insure anything within 50 yards of it. I like big and stout handguns, and hold them all the same. I use the basic Weaver grip. Primary (right) hand on the grip, elbow bent to the side. secondary hand holding the primary hand lower on the grip. With heavy recoil guns (the plr ain't one) this reduces the pivot of the gun against the web of the thumb/hand. Left elbow is held lower, and the gun is, if I were standing straight, at about 11 o'clock. My head is turned so I'm looking down the sights, focusing on the front site, not the target. Take a breath, let some of it out, and let the preasure on the trigger pile up. You can type this all day, read this 100 times, watch youtube 1000 times, but unless you practice this (some dry fire, most hot) it won't work. It is all mind over gun, in my book. It is easy to dry fire at the screw on the light switch across the room and have the gun not twitch. It is different when you know you are going to get hit with a solid punch. Take that hit. Don't flinch. At some point, you change from "but it's goin to hurt me" to "buahhh ha haaa!!!!". When you get to that point, it gets a lot easier to do. I wish my plr had a s/w quality trigger, but it don't. I wish I had a .223 barrel for my t/c, but I don't. I do know that time spent shooting .22lr WELL translates in to real rounds being shot better.
I dont' know, I've had a few vodka/cranberries, and I'm ready for bed, but did this help any?
Take care and be safe,
