I had a 9mm I picked up in the 90s. It was taken in a break-in. When I went shopping for a replacement I was considering 9, 40 and 45. I went with 40 back when it was fairly easy to find and 9mm and 45 weren't. The gun I also liked the best came in 9 and 40, but the 40 could be converted to 9 (and 357). The 9 couldn't be converted to anything. I also liked the idea that I was upgrading in power. I think 40sw is pretty comparable to 45.
I have to admit the harsher recoil of the 40 (compared to 9 or 45) came as a bit of a surprise(purchased the gun without shooting it first), but its certainly nothing I can't handle.
I recently picked up a real cheap Hi-Point 9mm carbine. I really wish that was a 40 since I want to use it as a back-up deer rifle. I still will, but now I feel compelled to buy some overpriced +p+ stuff that is still weaker than standard pressure 40sw that I have sitting around.
Well my +P+ can do anything your 40 can do at $30 for a box of 50 rounds.
