Hello, after taking my PM40 to the range for break in, (and shooting like a spaz) I wondered if there are any ideas on training drills or aids for the .40? I see the Laserlytes and other laser type devices for showing a flinch, but what about other drills? I do not want to be reinforcing bad habits! No rails to mount devices on-I have shifted to 2 eyes open, and am going to practice practice practice smooth trigger pull, maybe balancing a coin on the front sights. Any hot tips on other drills? Is dry firing OK? Does anyone have laser type things they are selling? THANKS!
