I have had 4 guns in .40 S&W... ( sold a Wilson Combat 1911 5" gun in .40 S&W because I hardly ever shot it -- and a guy came along and offered me a lot more money than I paid for it - he loved it and didn't want to wait 2 yrs for a special order to come thru from Wilson... ).... but I still have a Sig 226, a Sig X-Five and a Sig 239...in .40 S&W.
If I was really going to carry a gun in .40 S&W, I would have kept the 1911.../ but I will occasionally carry the Sig 239...its small, light, easy to carry - and its as small as I can go and still have a gun that fits my large hands. So that is my choice in .40 S&W...
The bigger picture for me ...is I'm kind of over the .40 S&W caliber...and have moved on to a 9mm...especially in my primary carry gun ( a Wilson 1911 in 5" as well ).../ Sig 226 is too wide to comfortably carry IWB and Sig X-Five is too wide and way to heavy ( 55 oz ) - both fun to shoot ..but I've never carried either one. So to me, the .40 S&W is an in between caliber..and it gets left out in terms of what I carry.
If for some reason I change my mind on carrying the 1911 in 9mm ...I will carry a Wilson 1911 in .45 acp ...or other 1911's in 9mm.../ ..or a number of S&W revolvers in .357 Mag in 2 1/2" or 4"...and they all get carried more than even my Sig 239 in .40 S&W.
I don't like or want any of the poly frame gun options...but its up to you, what fits your hands the best....no a consensus / or what suits me the best. Buy what you want ...what fits your hands the best...with the controls, etc you like the best.
