It seems that high pressure cartridges that are designed not to chamber in barrels that are marked for their low-pressure equivalents, do better on the market.
Eg .44 Mag, .357 Mag.
But for .45 ACP and .45 Colt, their +P equivalents are not designed 'not-to-chamber' in pre 90s guns.
That in, my view, is holding back .45 Super and the 33K PSI .45 colt rounds.
Is there a clear 'universally' accepted designation for recently manufactured guns that clearly state that they will work with .45 Super and the 33k PSI .45 colt rounds?
