Sen. John McCain is recommending at the U.S. Army throw out its current plan to replace the M9 service pistol until it can decide upon a specific caliber and type of ammunition soldiers need.

The chairman of the Senate Armed Services Committee blasted the Army’s Modular Handgun System, or MHS, effort in the latest in his “America’s Most Wanted: Indefensible” report series.

“The easiest solution would be to allow Army divisions or even brigade combat teams to select from handguns, ammunition and accessories that are already tested, approved and are being used in combat by units within the U.S. Special Operations Command and the Joint Special Operations Command,” according to the report.
