When an Army colonel is promoted to brigadier (one star) general, their promotion ceremony typically includes the pinning of their star by a family member and the presentation of the General Officer pistol and pistol belt. The latter, a thick black leather belt with an 18-karat gold-plated buckle and imprint of an eagle, was first produced in 1944. The rig is worn at the discretion of the general.
As for the GO pistol, the first issued were Colt 1908 .380s in 1943.
Then came Rock Island Arsenal-made R15 .45ACPs in the 1970s before Beretta M9 GOs became the standard in the mid-1980s. All have had special “GO” serial number ranges.
Now, Sig Sauer has a GO pistol model that is part of the Army’s handgun switchover as of late.
And to get more on that, I reached out to Sig. More on that in my column at Guns.com.
