OK, so I have been very spoiled by my 19, perfectly spoiled. I shoot it reasonably well and can do lots of range time without an issue. The 43, while snappy, has been tamed and for close up work, it would do the job. The problem: The stinker tears up my trigger finger. I am only good for 25 rounds and then I switch to something else to shoot. It has less than 500 rounds through it. Suggestions, aside from building a callous?
