Colt .22 Conversion unit

[mec]

A relic now I believe. It has a floating chamber and is pretty much the upper unit of the old Colt Ace pistol. It has no great reputation for accuracy- unlike some of the newer units from Ciner etc and the floating chamber tends to fill up with lead:

This one is sitting on top of an Ithaca 1911 A1 frame. I shot this target at 15 yards :

mine seems to be reasonably accurate.

i have it fitted to one gun, though.

I also have one that works well and seems reasonably accurate. I've shot it a lot. I did have it jam up badly once when the floating chamber sort of soldered itself together with lead shavings. But that was after many rounds witihout a cleaning, and since got it apart and scraped the lead out it has been fine.

How is the recoil? Isn't the floating chamber the type that is supposed to mimic full recoil? Never played with one but would really get a kick (pardon the oh-so-obvious pun) out of a 22 that recoiled anything even remotely close to a 45.

That recoil thing was the stated purpose of the floating chamber but It seems a good bit milder than ball loads. It does kind of mimic the recoil sequence of the locked breach .45 though

I had mine fitted nice and tight on a Safari Arms stainless frame , had a new barrel bushing installed and lapped a new crown on the barrel and mine shoots very nice, even with the bulk ammo.

I have found that after a few hundred (more like 500 in my case) I need to make sure the floating chamber is clean. If the floating chamber doesn't seat back into the barrel and you fire another round the gap is filled up with lead. I just check the floating chamber and when it starts to get slugish it is time to clean it.
