Well, getting back to the subject at hand, if a revolver, I'd go with either the S&W 686 First choice) and the Ruger GP-100 as second choice. I believe the S&W will have a better trigger that the Ruger which should make it easier to shoot. (I've had both and the Ruger was the firt to go. The 686 4" was sold very freluctantly as I shot it well, but mioney was needed. I miss that gun.
As to the semiautos, my first choice ain't there.
The good old 1911A1.
So, looking at what you have to work with, my first choice would be the SIG. I have a P-220 in .45 ACP and it's a real sweethert. I also have three very expensive custom 1911s and the SIG will not only shoot right along with them, but sometimes outshoot them. The Ruger P-85 I have shoots very well, is accurate enough, but doggone it, it feels like a brick in my hand. I ahven't played with any of the smaller and lighter Ruger so won't comment on them.
I like the 9mm and my night stand gun is an S&W 6906 loaded with 115 gr, Standard Federal HP's. (9BP) Still, Ialso have a 12 ga. shotgun under the bed loaded with alternating 00 and #4 buckshot, 8 rounds to be exact.
However, while I am prepared to repel boarders, I'm not in a job that requires being armed for my personal safety while performing my job.
My choice would be either the SIG or if they're on the list the Beretta in .40 caliber. Bigger holes let out more blood and let in more cold air, and that's what you need should, Gog forbid that you would have to shoot.
So why the 9 as a night stand gun. because my wife has too much trouble with the .45's recoil. Either the Colt Combat Commander or the P-220 are right close at hand for my use.
Here in Tucson, we don't worry too much about winter clothing for at least 10 or 11 months out of the year.
Go either .357 mag. or .40 S&W. I'd pick either one given the choices at hand.
