Relative to todays designs, yes it is. It's an older design, which as others have said elsewhere is from a time when labor and materials were cheap, and technology was expensive.
No one will argue it can be used effectively, especially where FMJ use is required, but there is no getting around it being an expensive design to get right.
2 things to keep in mind, with GSA/DoD procurement contracts like this-
1) they are almost always inflated somewhat above the equal item on the civi market- (part of the sweeten the pot bit, for the contractor)
2) they include large amounts of spare everything (barrels, slides, frames, trigger groups, magazines, etc.) rather than just a price-per-gun package.
Most of you would crap yourselves to see what the DoD pays for the M4 lol. you could buy a Caddlilac for what one M4 costs. lol.
Expect more to come - Army/Navy, before long. They've already spec'd the next U.S.-issue pistol's min. requirement be a .
45 or greater caliber.
Army's been throwing fits for something
OTHER THAN 9mm for decades, but hasnt been able to due to politics and budgets...
