Orion8472,
Well I figured it was for carry. I asked "how thin" to get an idea of what you considered thin. Some consider the M&P line thin.
It's also why I mentioned you may need to compromise some to get the 9mm you're looking for.
By the way, 1911s are thinner through the area of the slide than guns you've mentioned as being thin. They are just over .915 thick or so. Less than an inch. Through the area of the grips just over 1.200 with thin grips. This is thinner than most da/sa guns on the market and thinner than most polymer guns in 9mm. But they aren't what you're looking for so I didn't mention them.
Though I should mention the ParaOrd LDA guns. A breed of da/sa 1911 based guns.
I recommend you go to as many stores as you can and hold the guns in your hand with an eye to CCW. It's only in that way you will be able to feel the difference for yourself.
A lot of folks have recommend specific ds/sa guns to you. Now go take a look.
