I love 10mm, but I don't care for rimless cartridges in a revolver. I think of 10mm being the .357 magnum of autoloaders. I have a 1911 in 10mm, AFAIC it's a perfect combination. It's not as hot a load as .41 Magnum, even though the bullet weights can overlap. I prefer 10mm with a slightly lighter bullet, I shoot 155 and 180 grain loads. A 155 from a 10mm is similar to a 158 from a .357 in both mass and velocity at full power loads, although the .357 is a bit higher SD, which should give superior penetration.
