I am a conceal permitted woman in Texas, my choice of firearm is the P239 SIG 40. I had considered the Glock but didn't like the "light trigger" action of the Glock and feel I have better control of the SIG. I also added the Siglite night sights as well.
I hope that you are aware that you can purchase a .357SIG barrel, to "convert" your gun to another caliber (.357SIG). You can use the same magazines, I believe.
I have one of those myself - it's just a fantastic gun. I just took it out to the range today, as a matter of fact. I bought it at a gun show back in early December; I actually went thinking I was going to come home with a Glock 27, but I didn't like the way the Glock felt in my hand. I tried out a number of compact .40 calibers, including the CZ 2075 RAMI and the Springfield XD40 (another very nice gun - it was a very close second to the SIG).
I just got my Florida concealed carry license Wednesday and I'm now looking into concealed carry holsters. I'm finding that's a harder decision than selecting the gun!
