My sidearm

Sometimes, I think that carrying a 10mm automatic pistol as my sidearm is excessive, but that is what I like. Using a pistol of this caliber is only feasible due to the recoil reduction mechanism that is part of this particular weapon. The whole concept seems like a device invented by the mythical engineer named Goldberg. I like the 10mm caliber, as it is a "good stopper". This was the same rationale for the American Colt .45 M1917. For trench warfare, they needed a weapon that would drop an opponent. A smaller caliber might not do the job reliably.
