Why do I carry a 45? Because they don't make a 46 LOL.

I own both and must say I find it harder in follow up shots with the 40 then the 45. I have no worries carrying either round. I also carry a 9 and still carry a 38 revolver. Funny thing is be it 38, 9, 40 or 45 put it in the right spot and watch them go down.
