besides kimber and sti does anyone know of 22lr conversion for the colt gov..
i have a colt series 70 that is 9mm and the kimber only works on .45's.
also i want one made of steel not aluminum like sti and kimber. the only steel conversion unit i know of is the CZ KADET but of course it won't work.
 
Colt factory .22 conversion units....

There are factory Colt .22 conversion units. Out of production they can still be found in used/exc condition, though. There's one in the EE right now. Link here:

The Colt units are great. I've had one for many years. It currently sits on a Springfield Armory frame:

Don't get confused. Kart quit making the 22 conversion in the early 1980s, and extremely few made it to Canada - still find them in the US but asking prices are $600 and up. "Marvel" is the confusion point. Bob Marvel designed the first version, and it is still manufactured by Marvel Precision - this is the one usually referred to as the one with the best accuracy. Bob left that shop and went on to design a second version which is very similar but has a steel insert for the slide lock - this is produced by Advantage Arms in California, along with a Glock 22 conversion. Marvel now runs his own shop somewhere in the southwest and reportedly either "makes or tunes-up" his last design - but his delivery time seems to stretch into years. The police supplier (name escapes me right now) in Markham imports the AA Glock version but apparently not the 1911. STI imports the AA 1911 full slide version, but apparently not the "Target" version.

+1 on the Colt unit... not only are they steel, the floating chamber actually creates a bit of recoil (if you can call it that). Mine as been trouble free.

Speaking of Colt units, anybody tried the Kimber polymer magazine in theirs? It's suppose to work alright...

At about 1/3 the replacement cost of a steel one...

colt used to have THE COLT ACE a 22 version on the 45 but i heard not all that accurate and i am not sure but occasional feeding problems. couldn't have been that good they weren't around that long unless of course it just didn't take off. ammo at that time was cheap and surplus was available.
 
Definitely not as pretty as NAA's above, but it sure works good. Of all the .22 pistols I've owned/used, the Colt conversion is the winner, and last Sunday was the first time I'd tried it out.

That being said, I've never tried any of the other 1911 conversions.
 
Ive heared great things about the Kimber 22 conversion as well. Does anyone have any insight on how the Colt and Kimber match up?
Im also hoping that blueline gets there GSG 1911 in sooner rather than later. If that is a good unit i might opt for one of those. Its around the same price as conversion kits, and ive heared the slide will mate with other 1911 frames, so you get a whole gun for the same price.
 
found out the kimber units are made by CIENER. they have made for other guns such as browning hi power but i can't for the life of me remember for who else. kimber says it will fit any gov't model as long as it is in .45.

1. Colt made the .22 conversion units for many years.

2. I've had two different units now. Both were extrememly accurate.

3. Feeding problems, or complaints thereof, are linked to the floating chamber models. The floating chamber can gum up after a few hundred rounds of certain .22 ammo. [Mostly the heavily waxed brands]. Feeding issues are neglible if the unit is kept clean. [Same goes for most auto loaders in general, no?]

4. I suspect the Colt .22 units were discontinued when production costs started to outweigh demand & profit margins.
