converting a 1911 from .45 to 9mm? Login/Join

Hi All,
I'm familiar with the conversion options on the P-series guns but was wondering if a Sig Super Target in .45acp could be converted to 9mm with a Sig barrel from their 1911 9mm handguns.

Thanks,
Andy

I believe the breech face in a .45ACP slide is different, as is the extractor and ejector. You're not just going to be able to switch barrels and have any assurance of success.

It isn't a barrel swap. As said the breech face, ejector, and extractor are all different. I may not be economic to convert the two.

I'm pretty sure the frame is different too. The 9mm uses a ramped barrel I think.

I know it was going to be expensive when I looked into it for one of my GSRs. So much so it was more cost effective to buy a 9mm 1911, so I did. Maybe a switch to 38 super would be easier?

A switch from 9mm to 38 Super, or 38 Super to 9mm is pretty simple.

Also the feed ramp angle that is machined into the frame is different.
