Colt 1911 conversion kit troubles

I have a .22 conversion kit that I have been using on a SA Mil Spec with no problems. Tonight I tried to put conversion kit on to a Norinco frame but couldn't get the slide stop holes to line up. The conversion kit does not have a barrel link but a block with a hole in it.
Am I doing something wrong?
 
Will it go back on the SA?
Should work fine on the Norinco...you are probably missing something obvious.

Interesting.... Is it an actual "Colt" factory .22 conversion unit or another makers?

Also, which series of Norinco 1911 frame are you trying it on?

I have a Colt .22 Conversion Unit and one of the older series Norinco 1911A1 single stack frames. I will try it tonight & see if it works with it. And I have one of the new series Norc 1911A1 single stacks coming from Can-Ammo, when I get it I will also try it with it.

But it should work..... as the Norc 1911A1 single stacks are supposed to be "mil-spec" dimensions. I know the Colt .22 Conversion Units [and I have had a couple different ones over the years] can be a bit finicky to get on a frame. They have their own blade type ejector piece for ejecting the .22 brass that can be a bit of a pain to go on right. And as stated, the part on the .22 unit barrel that the slide stop goes thru is a "block" & not the link setup as on a standard .45ACP barrel. So, that can also be a bit of fun lining up.

Could be that block part on the lower end of the barrel with the hole thru it for the slide stop is not slotting into the cut for it in the frame properly when you are trying to put the whole unit on the frame?

Seems to me it needs a bit of fitting.

Even domestic firearm parts aren't always a drop in fit. I'd assume foreign built guns wouldn't have the same tolerances, probably even have a different internal design. Maybe norincos internals weren't QC'd for a 22 conversion kit to work in reliably.

My Kimber conversion kit fits and works flawlessly on my .45 Norinco 1911 Government. It won't work on 9mm Norinco 1911 though.
 
It is an actual Colt conversion kit and it does seem to be a fit problem. I removed the ejector and things lined up no problem. Replaced the ejector and it would not move far enough to the rear to line all the holes up. Will take it to Cape Custom later this week to see if they can fixer up.
Not sure what series of Norc I have but it is the one with the nice blueing.
 
My Colt unit is just fine on my NP29 9mm; assembles easily and precisely. Fits better than the 9mm top end. Very smooth, wobble free fit of slide to frame. Accurate.
 
I tried my colt conversion on my norc frame and the ejector that comes with the kit won't allow the slide to fit on the frame. I was going to compare the frame to the colt and see what the difference is, but never got around to it.
 
Dan, here is a pdf from Colt http://www.coltsmfg.com/cmci/downlo...iber Conversion Unit SemiAutomatic Pistol.pdf

I tried to put it on again, and the problem is the barrel won't fit back far enough for the slide stop to enter the barrel link. It's about 1.5mm too far forward. I think the problem is the ejector in the kit is hitting the ejector on the frame. (confused yet?) The ejector on the frame seems to be extended on the norinco's, compared to the original colt I have. Same problem as CZ Canuck
 
Took my frame into Cape Custom this morning. Seems the problem is that the .45 ejector on the Norinco frame sits a few one thousands of an inch too high. Therefore there is not enough clearance for the .22 ejector.

Dave is gonna take care of it for me.

Thanks. You probably need a 45 length ejector, yours may be an extended or different caliber version. - dan

It't completely stock, and other Norc's have the same length...I'm not sure why they use the extended, but I assume it's for reliability.

I never thought of that! It would make sense now that I think about it. I just assumed the conversion ejector had to fit in front of the frame ejector, and not ride over top. Time to haul out the grinder! (after confirming measurements, of course ;))

:eek: The file, you mean.
 
But...But...I loves muh dremel! :D

Okok, no dremel. I measured the ejector against my original colt 1911 that the kit fits on, and they were the same height. I took another look at everything, and figured that the ejector on the Nork is longer than the colt, so the ejector insert that comes in the .22 conversion kit needed to be modified, as it would hit the ejector, and not let the barrel back far enough to insert the slide stop. Soooo I decided to modify it.

**warning** The original colt .22 conversions are worth a bit of cash to collectors. Don't do this if it concerns you. Personally, I like to shoot mine, and that's where the value lies with me.

As you see by the picture, by taking a hair off the ejector insert from the conversion kit (cut shown in red), it will allow the barrel back far enough to fit the slide stop. I just went slowly with a file and tested now and again until the barrel went back far enough. I got it all buttoned up, but haven't gone to the range to test. It fed and ejected some rounds properly though.
