The P250 is what I fired the .40 out of. It's my dad's and he says it kicks more than his 1911 in the Navy.
Then again, maybe it's that he hasn't really fired a gun since then and he's not getting any younger. Don't tell him I said that!
Anyways, the .40 is a blast but just a little too powerful for me to control at this point for any kind of combat situation. That and the Double Action trigger pull is so long and fairly heavy so I lose my accuracy after a few shots.
That said, I'll have to try a .45 at some point since the .40 is so fun to shoot in and of itself.
