It’s the only super I’ve owned that would feed any ammo you gave it. They don’t show up that often, much less the model that has the mag release in the 1911 location.
Magazines tough to find too.
mine has the heel release. took some getting used to, but i got it figured out, and am pretty quick with mag changes. i hear you on mags glad the one i got came with 4. i find them occasionally, but they’re usually around $60 each. that’s one advantage of the heel release though- you get used to holding onto the mag rather than just dropping it.
i’ve also got a colt commander in .38 super, never had a problem with either feeding- they even do great with my +P handloads.
