Frequently Asked Questions

What is the primary difference between 10mm Auto and .40 S&W?

The 10mm Auto is a significantly more powerful cartridge than the .40 S&W. The .40 S&W was developed from a shortened 10mm case by the FBI to reduce recoil and fit into smaller frames, effectively creating a less potent round.

Did the FBI choose 10mm over .45 ACP?

Yes, following the 1986 Dade County shootout, the FBI initially chose the 10mm Auto over the .45 ACP due to its perceived effectiveness, though later reduced its power to create the .40 S&W.

Can 10mm ammunition penetrate Level 3A body armor?

According to testing in this video, Spartan Armor Systems Level 3A soft armor successfully stopped both 200gr FMJ and 135gr JHP loads fired from a 10mm Auto handgun, indicating it provides protection against these common 10mm rounds.

What causes reliability issues with some 10mm ammunition?

The video highlights that certain steel-cased ammunition, specifically Winchester USA Forged, can cause reliability problems like stuck cases in firearms such as the Smith & Wesson Model 5906, impacting overall performance.
