Hello tgt-USA. I have a commander in 40S&W / 357 Sig. combo using two barrels. I had the 357 Sig in at my last range time. That Sig is like my 40 S&W it will chamber anything I have tried. In fact a 9MM round somehow got mixed in with the Sig ammo. It went right in the chamber and bang another bullseye. There was a lot less bang. I checked on the floor and there was that 9MM case it had grown in size but that old 1911 just handled it with ease. If you build them right they will do the job. PS. I need to pay more attention to what I stick in my magazine cause a 9 MM don’t look nothing like a 357 Sig.If at all feasible, I'd try just using different magazines. An old fashioned feed ramp might defeat the best of magazine designs ... but I've yet to encounter that for a .45ACP.
Taking my own advice for a .40S&W that's having difficulties feeding truncated-cone target ammunition*. Ammo selected to have a similar profile to JHPs ... but unfortunate in tending to bite the feed-ramp and, apparently be set-back by that impact. Deducing the set-back because ~10% of the FtF cartridges are difficult to chamber even by hand after; case-mouths slightly flared. So right now I'm going to order some CMC "Power Mag" examples to see if that fixes it.
*- the same pistol feeds 10mm perfectly ... but different barrel and recoil spring doing so.
