If a single stack 40 is what you want OK, but have you shot any yet? there are several single stack 40s that conceal well, my wife and I had both a Taurus PT 740, and a S&W Shield we also had a 9mm Taurus (709) there are others and I'm sure there great weapons, but dam have they got a sharp recoil, to the point of painfull after several rds at the range, IMHO those guns are way to light for the 40rd, if you just want it for CC fine but one problem I and my wife found was you have to be mindful not to flinch on follow up shots which is tough knowing the guns really going to give you a wack, I have a Glock 23 and 27 carry both shoot both have ran over 200 rds through the 27 at one session with no problems, hell the small 45s don't wack you like the 40s, of which I have 2 a Kimber Ultra CDP ii and a Colt Defender, if I don't have a Glock on I have one of those, sometimes one of each.......so if it were me I would give a good look at one of the small 45s or subcompact 1911, much more pleasant to shoot and it still has more the enough power to take out the average BG
