Skinner definitely makes a difference in concealing and overall comfort IMO. My first EDC was a single stack. I could carry that baby wearing almost anything...
I was gun shopping for my current EDC when the Shield came out, I didn't realize at the time it was hard to get as my store always seemed to have them in stock. I must have gone on at least 3 or 4 different occasions to try and make up my mind between the Shield, the M&Pc and the XDsc. Personally, I finally ruled out the Shield because I couldn't rent it and I wanted to shoot what I was going to buy since I'd just sold a gun I didn't enjoy shooting. I loved both the M&P and the XDsc as rentals and ended up with the XDsc. I still love it...but it's much harder to dress around than the single stack was, at least at my size. While I throughly love my double stack, there are days when I've tried on my 3rd outfit and am still printing that I wish I'd gotten the Shield. I keep telling my husband, while I'll never sell one to buy one again, my next purchase will be either a Shield or an XDs just so it's easier to dress around,
