Not So Super
I have always liked the SUPER, but it does have some negatives.
One reason for the .357 SIG is that the SUPER is too long for a 9m.m. sized gun. The same problem prevented the .45ACP and 10m.m. from being used in many of the 9m.m. pistols out there during the 1980's.
During the 1970's, a somewhat popular conversion of the SMITH & WESSON model 39 used a new barrel and extractor in .38 SUPER. The ammo could only be used with 90 grain bullets or the round would be to long to function.
Another problem could be the rim. The SUPER is based on the earlier .38 ACP. Both rounds have a semi-rimless case if I remember correctly. No big deal in a single stack, but it could cause feeding problems in a double stack magazine.
Last, is the liability problem. If you shoot some SUPER in an old COLT, it may explode. For ammo manufacturers, that is not nearly as appealing as a new high pressure round that will only be loaded in modern guns.
Just my take on the SUPER.
