The 1911

1911

The Colt-Browning United States Government Model of 1911 .45 automatic pistol. Loosely, any pistol that uses the same design. Designed by John Browning, the 1911 is the best-known of his designs to use the short recoil principle in its basic design. The pistol is widely copied, and this operating system rose to become the preeminent type of the 20th century and of nearly all modern centerfire pistols.

TMJ Or Total Metal Jacked

Stands for Total Metal Jacketed, a term used by Speer to describe the full-metal-jacketed bullets in which even the base is jacketed. Total metal jacket bullets, often referred to simply as "TMJ", are the most widely used bullet type at indoor ranges and among competitive shooters. The reason for this is a simple one but important: The normal full metal jacket or FMJ bullet has a small amount of exposed lead at the base of the bullet while the TMJ does not. The TMJ surrounds the otherwise exposed lead area with copper.

Trigger Break

[trig-er]   [breyk]

  • The point at which the trigger allows the hammer to fall, or releases the striker, so that the shot fires. The ideal trigger break is sudden and definite. "Like a glass rod" is the cliché term shooters use to describe the ideal crisp, clean break.
Trigger Job

A process of lightening and otherwise improving trigger pull by means of polishing and reshaping the engagement surfaces. Can be dangerous unless performed by a qualified gunsmith. A trigger job usually involves polishing, and in some cases squaring off the engagement surfaces of the sear and hammer, along with other surfaces that are involved in the action of pulling the trigger in order to smooth it up.

This is usually done by a gunsmith because they have the proper tools and know which areas need to be touched up as well as having the knowledge as to how much to remove without making the gun unsafe.
