Surprised the military, even as highly trained as SEALs are, going with a sidearm with no manual safety.
The Army has been using Glock 19s in their Special Ops team training for a while. I think they have an option of using the Glock or the M9 when deployed, but I know for a fact that they train with both stateside. I spoke with one Green Beret that was just finishing up a pistol course and he said they start the course with a choice of the Glock or M9 and use a brand new pistol. By the end of the course, the gun has many thousands of rounds through it with some days seeing more than a thousand alone.
I'm guessing that the military is fine with the Glock for specialized troops, just not for the regular soldiers.
