The ballistics of the10mm is nearly identical to a 357 magnum. 357 magnum ammo is half the price of 10mm.
You can practice all day long with 38spl ammo for cheap.
Back to the 45acp vs 10mm, the 2 calibers are identical out to 180 feet. The government did a study and determined one shot of 45acp would kill a cow.
I already own a 45acp and a 357. Why do I need a 10mm?
