That's a good question. I just threw out the idea of a kit gun without defining it. For me, the kit gun will be a gun I will likely not have on my person directly, but would be a gun that I'd have in my backpack or car. It'd be a gun that I can have 100-200 rounds handy, mostly for plinking purposes. It's for busting out whenever I have the chance to put a 100 or so rounds through it. Keep in mind, I don't need a super big gun, just a gun I'll have with me.
And I want it in a smaller form factor than a full-sized .22 LR pistol: I have a 22/45 Lite for a full sight radius and better trigger. However, I do want it to be a fun to shoot gun and I plan on putting 1000's of rounds through the gun.
Ideally, it'd also be a gun that I won't have to worry about damaging (which is why aluminum or alloy frames are kind of out). The LCR-22 very well may fit this bill, as it is small and is probably pretty sturdy. While I realize a 4" barrel would make a better shooter, the idea is to have a smaller over all package. Micro .22 LR semi pistols aren't something I want to mess with, but a short barreled revolver should run anything under the sun.
You guys have given me lots of options, and many would fit the bill. I'm still charmed with my idea of chopping a 4" SP 101, because it would probably still be a good shooter, especially with a little trigger would.
For primary self-defense, I've got a Kahr K9 for CC.
On the 317, it has been said, by Venom, that I'd ruin a 317 as it is AL.
