Why am I more accurate with .45 ACP??

Also, you prefer the recoil of the 45 because it is more like a big shove than a 9mm which is more like a slap.

I'd have to agree. I find the .45 acp recoil to be much more manageable than the .40 or the 9mm +p. I found myself more accurate with the .45 acp, too.

I spent a lot of time practicing with the 9mm, until I was as accurate with it, but in a more concealable package. It worked, and I carried a Kahr P9 for a while. But ultimately, I found myself back with a Kimber Compact and/or a grip-reduced Glock 36, still very concealable and oh-so-much-more accurate FOR ME.

If it works, go for it.
