I'll bite... (beware, some will accuse you of just trying to get your post count up, so, /flamesuiton)
My favorite gun this month - Ruger Gp100 4" 357
Overall favorite --- I would betray my youth if I didn't say it was my old 10/22. Many gophers and rabbits in ID, MT, and UT fell to that awesome little gun!!!
I'll agree with Throttle... Either my 10/22 or my Kimber 1911. Though my Grandpa's Webley MkIV chambered in 38 S&W has a special place in my heart.
So to redeem yourself Johnny, (and to get more QUALITY posts) what is YOUR favorite so far, and why*?

Favorite semi-auto handgun would be my Springfield 1911. Favorite revolver would be my S&W Model 66 snubby. Favorite long gun... Well, that's considerably tougher to determine. I guess of my centerfire bolt guns, my Carl Gustaf Swedish Mauser M96 would be at the top of my list. 22's - that would have to be my Mossberg Model 46B. For semi-autos, it would be my M1 Garand, although my FN 49 is close on its heels.
