The STI International Sentry .45 ACP M1911 Pistol

In 2011 the John Browning designed and Colt manufactured Model 1911 pistol in .45 Automatic Colt Pistol ( ACP ) calibre celebrates 100 years in existence. Adopted in 1911, this pistol was the standard US Forces sidearm until it was replaced by the Beretta 92F in the mid 1980’s. Some US Special Forces units are still carrying the M1911. This pistol has seen a lot of developments in the availability of customised component parts and methods of manufacture.
