Although I haven't bought a Sig yet, I'm planning on it within the next week or so, provided I can still find a 239 around here. I've decided to make the jump into a Sig (and a big(ger) money gun) because I've heard nothing but good things about them, and seem to have an excellent reputation.
I'll be getting my CCH permit around the first of the year, and right now my carry options are a Beretta 96FS (way too big), a 1911 (Charles Daly piece of shat that I wouldn't trust my enemy's life with) and a Springfield XD-9 subcompact.
I bought the XD back this Spring thinking it would be perfect for carry, and I'm sure I will carry it, however I don't like the fact that it doesn't have either a manual safety or a decocker. The Sig has a decocker, and feels excellent to me as well. I'm planning on getting the .40 cal, which will allow me to buy a .357 barrel and shoot that round with it, IF I ever decide to. I've also been told that I can drop a 9mm barrel, recoil spring, and mags and I'm set for a cheap range shooter too!
Anyway, that's kinda how my mind's thinking right now. Oh, and the fact that every frickin' movie I've seen lately has Sigs out the wa-zoo in them!!! It's driving me crazy!!! It's also driving my wife nuts, because every time she watches one of those movies with me she hears me muttering, "I want a Sig.......I want a Sig baaaad."
