No. I had a chance to shoot the 9mm and 40 before buying it, and it felt great in 40. I like the 40 round a little better than the 9mm, and I have a few more 9 mm than 40s, so time to even it out. I enjoyed shooting it so much that I ended up putting 150 round through it (that is the most I ever shot a new gun at one time). I had no issues with it. How often did that happen?
