It's still lost money, chump change or not. It doesn't matter.Glocks market is global, Mil/LE all over the world and civilian. Giving up a small % of US civilian market to the M&P. Would be chump change. Compare it to British contract and the likely US contract in the future.
Glock will never get the main U.S. Military contract for a sidearm. The military brass wants an external safety at least. Which I think is stupid. I would support glock 19's being the sidearm of the military.
im a nobody in that decision so it doesn't matter what I think.
