“The 10mm was the right cartridge, introduced in the wrong pistol ... then the FBI caved in to the pansies, and we’ve been saddled with the .40SW ever since. It’s not a bad cartridge, but the full length, full power 10mm is better. It would also make a dandy carbine cartridge; IMO more suited to that purpose than the 9mm, .45ACP, or .40SW. “
I have read that the 10mm is even more destructive to the weapon than the .40 S&W is. All I can say is my Sig 229 .40 doesn’t seem to be affected by the round it fires.
Find yourself a reloading manual, and compare the powder charges, bullet weights, and muzzle velocities between the .40 and the 10. The 10mm is a beast. For reference, the .45ACP is also a beast, but of a slightly different sort. Both can be tamed, by appropriately designing the pistol. IMO, the 10mm is essentially a .40 Magnum, relating to the .40SW the same way that the .357 Mag relates to the .38 SPL.
the 10 is great but if you have to use it the cops will take it away and good luck getting it back in good condition, if at all.
