I only argue (humbly and respectfully) that not just any-old 38-Super round will chamber in any-old 357. Certain rounds produced by certain manufacturers work....others not so much. There are several post here in the thread above that attest to that. It has to be a little undersized round, or a little over-sized chamber...or some of both.

I understand that the popularity of the round "south-of-the-border" is due to the fact that citizens cannot own a gun chambered in a military round and the military round of choice in those countries is the 45ACP.

Hey.....just grab a 9MM revolver and be done with it. The 9 can be loaded-up to idiotic pressures, but you need a lot of gun under it to shoot it. The Russians did all sorts of crazy stuff to the 9x19....even had a body-armor piercing load and one that zipped along at a muzzle-velocity approaching 2,000 fps.

By-the-way....I too have had several Colt 1911's chambered in 38-Super and I love the round.
