I own several custom 1911 handguns that were purchased for personal protection. I like this new R1 UltraLight Executive from Remington very well-even more than my Nighthawk Commander. It has all the features most anyone would desire for concealed carry, and can be had for about a third of the price. After a month of carrying it, I am addicted to it. I’d suggest you give it a look if you’re interested in a 1911 for concealed carry.
