Smith 686+ (7 shot) - 4" - loaded with warm .38+Ps for home, .38s at the range, and several handfuls of "regular" .(Mix of 125 and 158 gr) 357 occasionally just to remember what it's like/maintain proficiency...and for woods duty if you're the sort to enjoy that too. I don't recall if you stated where you live, but here in the desert (but you could say the same for any of the southern tier states) - March through October, the first two chambers are loaded with snakeshot when out in no-legged country.
I disagree with the full size auto comment(s)--SR9 etc. Other than accessory rail (?)--and I believe the "c" will accept a light anyway-- it won't do much your "c" doesn't...I'm saying that with the luxury of knowing you already have the SR9c. That's the beauty of the SR9c, M&Pc, and others of their ilk,..with their accessory extendo grip/magazine (17 with the SRCc) they can double as a big boy. Get something different with (near) completely different capabilities, function, IMHO.
However, IF going auto, I'll +1 a full-size 1911. In .45 ACP. It IS "enough" different to spark your interest and can do the woods duty if need be. I still say it's easy: 686+ and be done with it! If budget's more an issue, find a used police/Highway patrol turn-in .357 (19, 66, etc--these like 158s better). J&G Sales, Prescott AZ as one good source,as may have already been mentioned.
