I've been looking into the sig 1911 carry nightmare. 4.2" barrel and bobbed frame. Still 8+1 aims has them advertised for 839.00
For concealed carry, I use a sig sauer sub compact .45.
I’ll be odd ball man out here… my favorite 45 carry is my Smith & Wesson 4516. Most will say it’s too dam heavy but after carrying a 20 lb duty belt for 38 years it’s nothing to me.
