E3B: I've been a fan of Kit Guns for a very long time, liking them on the trail for hiking, camping, fishing, and on my pack belt when big game hunting. Great for the coup de grace if needed, and the occasional grouse that sits 8' away in a fir, begging to come back to camp with me for dinner.
Granted, high quaility Kit Guns like the S&W's are getting more expensive every year. I purchased these two some time ago, and between the two, and the combinations they offer in terms of ammo types and capacity, have filled the bill 100%.
The first one is a 4" Mdl 651, 22WMR, that I ordered the 22LR cylinder from the S&W parts dept, then had my smith properly fit and time it to my revolver. All stainless, it's heavier than the Mdl 317, but holds better for delibrate shooting, and offers the choice between 22LR and 22WMR...nice.
The 3" Model 317 is only 11 ozs, and I don't even know it's there on my hunting pack belt, and offers 8 shots of 22LR Power Point. For summer hiking, this is the baby to carry. I had a local fellow make the thumb break holster about 30 years ago for my old blue Kit Gun, that was replaced with a 22LR M63 stainless (also discontinued), that was replaced with the M651 when I found out they were being discontinued (a sad move by S&W).
I found this new M617 Airweight at a gunshow for $350 a few years ago, I'm stunned to hear they bring five big ones now.
In my hunting pack rig, it's on my left side for cross-draw carry (I'm right handed) so as not to interfere with my rifle, and is about un-noticed in the field, being a virtual featherweight. The holster carries normally on my right kidney, out of the way and always handy in the field.
I'd shop around for used on the net to find a nice M317, as the Smith Kit Guns are top drawer, will last a lifetime, are made here in the USA with an excellent warranty, parts availability, and reputation for quality. Five big ones now???? Unbelieveable!
