Over the past 6 months I have been following the Marines sly procurement of M45 1911 pistols (formally MEU(SOC) pistol) in small parts. The Marines have just procured 150,000 rounds of Federal Premium Gold Medal .45 Auto 185GR FMJ-SWC Match Ammunition.
The procurement is notable because the rounds are not loaded with classic 230 gr hardball bullets, but the lighter and faster 185 grain FMJ-SWC bullets.
[ Many thanks to Matt for emailing me the info. ]
UPDATE: Daniel pointed out that the purchase was for the USMC Competition-In-Arms Program and that the solicitation appears to have been canceled.
