It's nice to see a company that hasn't whored itself out to sell a .40.
This is just my opinion and I have had both the 40 and the 45 but I think it is because the round has more energy than a .45 ACP in general, but with a much lighter bullet, (typically 180 grain vs. 230) so about 20% lighter, but with about 20% faster velocity. (900 fps vs. 1100 fps.After owning and shooting my 40's I have to tell you I was a little disappointed in my first 45 as far as recoil. I was expecting more snap. Especially with the 3inch. I like them all. They are all unique. Changing calibers and guns keep you thinking.
