Wonder if the Marines tried out the 21 or 30 so they could still have the power of the .45 ACP and the Glock simplicity?

I have a 1911 and a Glock 30. Probably grab the 30 if in a real hurry.

My thoughts exactly.

I thought the whole gripe about the 9mm was a perceived lack of knockdown power. The 21 provides .45 caliber in the Glock format with a relatively large magazine capacity(compared to the M1911). The Glock 19 magazine holds 4 more rounds (17 vs 13 in the Glock 21).

So, is 9mm now okay if you can carry 4 more rounds in the magazine? Or is the decision really based on conforming to the handgun types and ammunition calibers already used by the other special operation forces within SOCOM in order to simplify logistics and increase interoperability?
