Sounds like you want concealed carry, my first choice would be the Sig 239 as the ONE gun. 9mm Single stack, with a ton of options so you can suit the gun to you.
Anyways concealed carry is a very personal thing. What may work for one person may not work for another. Try them both, try the holsters available for both.
Personally I carry a Sig P228R and a Ruger LCP. The 228R is my primary, the Ruger is my BUG, or my deep concealment gun.
Anyways various responses to outrageous claims.
I cannot understand the logic of a DA/SA action, if you like the long pull of the DA then use a DA only auto. The transition from DA to SA, in my opinion is distracting and time consuming as you need to slightly alter your grip when the change is made. To really shine some light on the subject, competive shooters (IPSIC and IDPA) perfer two types of actions, single (1911 ) and striker fired (Glock, M&P etc) over DA/SA types as they are faster and the trigger feel is the same from start to finish. I have owned and shot both and I prefer the striker fired for it's consistent action.
You don't need to move your hand to transition from one to the other. You only need to do that if you are trained improperly.
As far as USPSA, again incorrect for quite a while the CZ 75 SP-01 was dominating Production. Until Team Glock redoubled it's efforts to win production. It's the shooter not the gun, the DA/SA transition is only on the first shot.
The Sigs Da/sa trigger is obsolete. The Glocks trigger can be upgraded into an excellent trigger very easy.
The Glock draws faster, is lighter, and smoother. The Glock can be repaired cheaply and quickly. Its about as tuneable as an AR15. Every single part for it is out there.....the best part is none are needed if you want to go that route.
DA/SA triggers are far from obsolete, they are probably one of the more common triggers.
Draws faster, never heard about one compare draw times. Unless there is some magical fairy dust on the Glock, the draw times should be equal give the same holster, and shooters of similar skill levels.
Smoother, I would beg to differ, Sigs are very smooth when properly lubed, and so are Glocks.
As far as tuneabillity, there are replacement parts for Sigs, they are concentrated mostly around the competition communities. In my Sigs I have aftermarket grips and grip screws, after market sears, and safety levers, after market guide rod, after market firing pin block, after market springs, and after market sights. The only reason why there aren't more parts replaced is because I didn't deem the parts necessary.
You may not see the parts in cheaper than dirt, but the parts are out there.
I can make most Sigs fail just by getting them dirty. If you are good about maintaining the Sig and clean it after each shoot you won't have that problem.
Eh? I've shot 1,500 rounds of CCI Blazer Alminum (dirty dirty ammo) at a range that was recently constructed with dust blowing everywhere getting into everything, zero failures, and I never cleaned the gun, or the magazines.
