I've been thinking about upgrading my wife's carry pistol. It's nice to know the Shield performed well, that one is on the short list. I really wanted the Remington R51 to be a contender, but it has been receiving very poor reviews.
I like the shield but am thinking maybe a XDS in .45 instead. I never liked the look of the R51 (I know I know but I have to look at it while cleaning and using it at the range. lol) and it seemed way to complex a system for a carry gun.
