Nothing the matter with carrying what works for you. It would be foolish to do otherwise.
I use to tell my students that there are more than one way to skin a cat. If a particular hold or stance worked well for them - enabling them to get fast accurate hits - then USE IT!
I carry 3rd gen 45s because they work for me. Very well. I chose 45 because of what I witnessed working robbery/homicide. When the day comes that I can no longer shoot 45s accurately and quickly, I will go to 9mm. I own several nice ones. Or maybe a 357 snub. I have a few of those still.
I recently reevaluated my handgun needs. Lets face it, my guns are getting older - as I am and like me, they have high round counts.
And after shooting Sigs, Nighthawks, Colts, Wilson Combat, CZ and several other makes/models I didn't find one that I could shoot as fast and accurately as a 3rd gen 45. I figure I have 10 to 12 years left of carrying a gun everyday......maybe.
So, I had a local Smith go through my 4506-1 "pawnshop rescue" a 4566 and a 4516. He detail stripped and cleaned them all. And told me that I have no issues or worrys with any of them. He certified them GTG. So those are the guns that will be used by me.
And of course the minute I come across a clean 4506-1 "dash 3", with adjustable sights, I will he buying it.
