The Beretta 92 is a series of semi-automatic pistols designed and manufactured by Beretta of Italy. The model 92 was designed in 1972 and production of many variants in different calibers continues today. The United States' military replaced the M1911A1.45 ACP pistol in 1985 with the Beretta 92FS, designated as the M9.
Designed for professionals, the GLOCK 17, in 9x19, is the most widely used law enforcement pistol worldwide. Because of its unsurpassed reliability, above-average magazine capacity of 17 rounds in the standard magazine, and its low weight, it is trusted by law enforcement officers around the globe.
A heckler is a person who harasses and tries to disconcert others with questions, challenges, or gibes. Hecklers are often known to shout disparaging comments at a performance or event, or to interrupt set-piece speeches, with the intent of disturbing performers and/or participants.
The SR series Rugers are some of them. As an Army ordnanceman, I've repaired everything the Army owned, 4.2" in caliber and less. The most fragile weapon I've ever encountered, and by a huge margin the weapon I've performed the most repairs on is the M-16 class of weapons.
