I've carried some version of a 1911 (3 1/2" to 5") since I was a teenager and love them but wanted to carry more horsepower due to the number of mountain lion and (less so) black bear in my area.
And to be able to carry 1 round of shot in the gun in summer months due to the rattlesnakes we often encounter in the yard where the kids play.
I've used .45acp shotshells for years but almost always end up having to clear a stovepipe. Not a huge deal but annoying.
I've developed quite a bit of affection for revolvers and have about 7 of them now.
A 329PD goes everywhere with me these days, but sometimes a 1911 as well.
Not having to chase brass is just an added benefit.
