I own 2 SIG's. One is the 2022 in 9mm. It is your basic unstoppable semi-auto. If one doesn't mind a poly frame, this is the literal bargain of the century. The other one is the Mosquito...the 22LR mate to the large caliber pistols. Lots of controversy on this one. It likes what it likes and insists on being clean. Both are typical high Sig quality, very accurate, very well engineered.
I've owned many exceptional handguns from Ruger singer action 44 mag revolvers, to a Colt Delta Elite 10mm, a Colt Python 357 mag,, other 9mm autos and 22's and 380's, etc, etc, etc. Of all these the SIG's play second fiddle to no one.
One either likes and does well with the Glock...or not at all. I don't like it. Doesn't mean it's not good... it's just not good for me. Gotta love the reliability, but the grip angle is all wrong for me. I like Colt/CZ paradigm. So the Sig feels right.
I also have a Springfield XD40 SubCompact. It's an exceptional pistol. Very small, high capacity, high power, very good at what it's supposed to do.
