What's wrong with the 40 S&W??????

[edgehill]

I carry a Px4 in .40. I also have a M&P9 that I shoot as well. When my wife and I are at the range, she usually shoots the 9 and I shoot the .40, but I do find I'm more accurate with the 9, but that may be because the M&P has a few extra inches, so my sight picture seems to work better.

When I shoot without sights, my accuracy is about the same.
