Anyone know if the frame on an RIA 1911 in .38 super is the same as one on a .45acp? I know the slide is different, but I am not sure about the frame.

I ask because I have done a fair bit of work to my RIA .38 super, and I am thinking that if the frame is compatable with I might just buy an aftermarket slide, barrel, ect and use that instead of buying a whole seperate gun for now(save on dros, no 10 day wait since the frame has the SN, that kind of thing)

Also wondering if any .22lr conversions like the Kimber one work on the .38super frame for the same reasion.

Frame should work BUT the extractor won't. The bottom line is it would be a LOT cheaper to just buy a 22.

PS...I don't know if RIA makes a conversion kit so I'm just assuming they don't.

I had the same question about the RIA frames. I was battling getting a whole new gun but if I can make the RIA a multi cal then that would benefit me right now.

I was planning on a whole slide, extractor, everything. For the .22 part I already have a ruger 22/45 just considering whether to get a .22 conversion or buy a GSG 1911.

from what i heard, the feed ramp angle is different between .45auto and 9mm/38super.

not sure on the conversion though. might require some fitting.

.38 super vs. .45 ACP ....

Different feed ramp angle (welding and re-milling = very expensive)
Different ejectors (replace and refit = cheap)

Net net....buy a new frame.

wait.. all you want to do is to be able to run a .22 conversion kit on your .38 RIA?

if so then the feed ramps do not matter in this case. the .22 barrel will come ramped. the only issue will be the ejector. there is a way to modify the .38 ejector to work with a .45 upper, so that means it will work with a .22 conversion that needs a .45 ejector.

or...
a.) buy a ria in 45auto
b.) buy 22lr 1911

I had the same question about the RIA frames. I was battling getting a whole new gun but if I can make the RIA a multi cal then that would benefit me right now.

I had a .38 super upper fitted to my Colt series 80 frame that originally had a .45 upper on it. It worked fine except that it would only feed round nose .38 super rounds. Besides the .38 upper I had to put a .38/9mm ejector and slide stop. A 9mm barrel never did feed 100%. The RIA should be essentially the same thing.
