"I suggest getting snap caps/
dummy rounds for any and all "dry" practice. They are super cheap, amazon."
^^ Great advice!! If I may add my two cents worth; With a dummy round loaded, point your weapon at a corner of your training room. The point is to keep the sights lined up on the seam of the wall as you squeeze the trigger. This will help you identify if you pull left or right and make corrections BEFORE you waste too much money on ammunition. Get to the point when you are able to CONSISTENTLY remove your weapon from its holster, point it into the corner, and have no movement when you squeeze the trigger. Once this is good, get some range time.
There was a post, not too long ago, about a laser system. If I had the funds, I think this would fit nicely into an exercise regimen.
