Texas Star, having owned a couple of Colts with the old style barrels, I always wondered how those Pre War Super Matches could have displayed anything like match accuracy. My 38 Super Colts, made in the '70s, were dismal! Replacing the barrel in my Government Model with one headspacing on the case mouth solved all accuracy and other issues associated with those old style barrels. Appreciated your comments on your experience with Super Match accuracy.
Tmnguuyen, I've used some of the types of ammo shown in your photo. I suspect the ammo by major manufacturers will work fine. Don't know about the white box 147 grain as I'm unfamiliar with that type. FWIW, I recently chronographed some of that Armscor 125 grain ammo in my Colt Special Combat Govt. with 5" barrel. It was the slowest and least accurate of the the several types of 38 Super ammo I've been shooting lately. Only averaged 1130 fps. Not much better than some generic 9mm ball I've tested. The Remington 130 ball averages 1200+ fps in a 5" barrel, as will the Federal American Eagle in my guns. The Winchester 125 Silvertip averaged only 1160 to 1175 fps tested in several different 5" guns.
I kept an eye out for a 9mm or 38 Super P220 with "American" style mag release at gun shops and big and small gun shows for ages, but never ran across even one of either caliber. In the fullness of time, I did acquire two unfired P220 9mms off different forums and have 1911 style Supers I enjoy shooting and reloading for. BTW, to realize the ballistic superiority of the Super over 9mm, you pretty much have to go to boutique ammo like Underwood, CorBon, Buffalo Bore, etc, or reload. Anyway, the P220s are fine pistols in any caliber. Enjoy!
