I agree with your feeding comment,
Tom Servo. Though I've never had much of a problem with either.
Nice piece,
Dahermit. Can't tell, alloy or steel framed? I've built up two over the years: one a Combat Commander .45 that I fitted (minimally) a .38 Super & 9mm Luger Colt slide/bbl. to. The 2nd is still with me: a Ruger CMD in .45 that is dimensionally identical to my previous Colt. Both fed and fired 9mm & .38 Super with only a changed ejector being necessary. BTW, the .38/9mm ejector works just fine with the original .45 bbl./slide. Of the three, the .38 is the most accurate, and too, it's POI is within 1" of the 9mm POI at 15 yds. Pic of the Ruger/Colt .38 Super. IIRC, those two slide/bbl's, (9mm & .38 Super) cost me ~$100 back in the late 80's from ads in the Shotgun News!
It doesn't make a lot of sense to me to buy a 9 round mag capacity 9mm 1911 when 17-21 round mag capacity is available in smaller, lighter guns designed around 9mm.
That's my thought as well. I'm a .45 ACP advocate, but do own a Series 70 Colt 1911 as well. It's a heavy gun for the cartridge but very pleasant to shoot...but again, limited in capacity if that makes a difference. An alloy frame Commander (the original Colt offering), does cut the weight, but again, it comes down to capacity...and that rings many modern shooter's bell.
I also have an all steel Commander in .38 Super, which makes more sense from my perspective...very high speed (1300 fps with a 124 gr bullet is no problem and doesn't stress the gun), and in my example, superb accuracy (sub 2" groups at 25 yds from a sitting position).
In my use, I reload only nickeled .38 Super cases...as they're flipped 7 ways from Sunday during ejection and the silver case is easier to find than brass in the long grass range. All in all, the Super's a better round than the 9mm Luger, more versatile. BTW, for those of you interested, .38 Super 1911 magazines will feed 9mm just as well, but not the reverse. And a .38 Super bbl. will (in most instances, a drop-in fit), will turn your ho-hum 9mm into a .38 Super tiger! YMMv, Rod
