I thought about getting a conversion unit for a while. One of the complete guns (Rimfire Target) sounded nice, but it seemed like a lot of money.
Then I ran across one at the regular shop for a really good price about two months ago, and got it.
If you look around the internet, you may see a lot of complaints of malfunctions with Kimber 22 conversions and complete guns.
Like a lot of things on the internet, I think you have to take that with a grain of salt.
Kimber makes no secret of the fact that Standard Velocity ammo may not function the gun. I noticed that most of the people with complaints didn't specify what ammo they were using. I'm not saying that every malfunction as caused by not using Hi Velocity ammo, but I have to wonder if it played a part.
Even though I knew better, I had to shoot mine with both Standard and Hi Velocity ammo. I had two malfunctions the first time- one was a boltover (slide passed over the next round in the mag without picking it up), and the other was when a round failed to fire on the first attempt (but fired on the second hit). Disregarding that last one as a potential ammo problem, that leaves one malfunction.
I have had none since.
Granted, I haven't had it that long, or shot it that much, but I would certainly not call it unreliable.
Accuracy is fine, also. I've never benched mine, but shot eight or ten types of ammo for group "at speed". From 15 yards, standing, unsupported, and firing as soon as I got a sight picture (which is pretty fast with a .22) I got 2" groups. Considering the speed the groups were shot, that's pretty good. Results were near-identical among all the different ammo types, with nothing standing out as being particularly good or bad (as can happen with some .22s). A couple went about 1/8" smaller, and a couple around 1/8" larger. It's nice to know that I can grab about any box of ammo, and be OK.
