terrydoc Posted May 15 Share Posted May 15 (edited) Hi guys just spit balling here but I have a .357 sig Para that I'd like to use as a 9mm, can I get a 9mm top end and run it on the .40 frame (9mm mags work ok in the frame)? Is there any reason thats not possible? Looking for cheapest easiet option, going to be a LO type division gun Edited May 15 by terrydoc Link to comment Share on other sites More sharing options...
RJH Posted May 15 Share Posted May 15 Should be able to. Might have to change the ejector Link to comment Share on other sites More sharing options...
xrrcr Posted May 15 Share Posted May 15 Same thing only different. Started out life as a RIA 40 ( Para Copy ).9mm Slide, Barrel, Ejector, Mags and then you're good to go. Link to comment Share on other sites More sharing options...
vegaspete61 Posted May 15 Share Posted May 15 i bought a Para in 40. I just bought a 9mm and a 45 acp tops ends. The gun runs with all 3 calibers...same ejector. Link to comment Share on other sites More sharing options...
Joe4d Posted May 15 Share Posted May 15 make sure the ramp is correct on the barrel. but best bet would be to find a para brand top end from same generation so you dont end up with lock up , ramp and barel link fit issues. 1911's are not plastic fantastics and arnt gonna be plug and play mixomatics like you can get away with from other more recent guns all made by same people on same machines.. 1911's are made all over the world with various tooling . So dont be surprised if things dont fit at first. Link to comment Share on other sites More sharing options...
tator2k Posted July 1 Share Posted July 1 I've swapped the top end between my P16-40 and P18-9 without a problem for either. Link to comment Share on other sites More sharing options...
ryan45kim Posted July 9 Share Posted July 9 I’ve got good news for you, Para ran the same size breach face on their 9mm and 40 S&W slides so all you really need is a new barrel. And yes you can swap the top ends between 9 and 40, the only possible issue would be the ejector. Paras are good guns, I ran one for years. I do miss the Canadian Paras.

terrydoc Posted July 9 Author Share Posted July 9 Ended up with a cheap 9m complete gun, the barrel in the .357 sig is a bull barrel so would have had to chase one of those , the 9mm was probably cheaper and the mags work also. So hopefully a good outcome once its milled. Link to comment Share on other sites More sharing options...
