I went through the usual Infantry-oriented Army Basic training with the M14 rifle, then eight more weeks of tank crewman training, MOS11-Echo back then, which included the use of the M1911A1 .45 Auto pistol that served this country's military for just a bit less than 75 years, about a third of the Army's and the country's existence.
Call it training, experience, or 50 years worth of satisfied use, [I'm still here, above ground and kicking!] but I believe in the .45 ACP too.
Great holster.
