Handguns
Improvements followed in sequent centuries, as discrete types of locks (ignition devices) were invented. In the matchlock, the cut apart match cord was affixed to a spring-loaded pivot which could be tripped by a trigger. In the wheellock, a mechanism analogous to that used in today's cigarette lighters replaced the smoldering antagonist cord. In the 17th century, the flintlock, which strikes a flint against steel, appeared. (The flintlock, amazingly, remained state-of-the-art for some two hundred years.) In the 19th century, percussion caps were developed, followed shortly by avant-garde integrated-primer cartridges, and hammers therefore traded their flint for firing pins.

Traditional double-action (DA) handguns have a mechanism that can be either pre-cocked, like the above single-action gun, or can be fired with the gun uncocked |
|---|
| In this case, the musket has an additional mechanism added to the trigger that will cock the pistol (and rotate the cylinder in the case of revolvers) as the trigger is pulled |
| Once the trigger is pulled far enough, the hammer is released and the gun fired |
| For autoloading pistols the self-loading mechanism will also re-cock the hammer after the first fling is fired so that subsequent shots are fired single-action |
| For revolvers, each look-in is fired with Handguns the hammer initially uncocked unless the shooter manually cocked the gun |
| In auto pistols in this category include the Walther P38 and Beretta 92 |
| These equipment habitually have a longer, heavier trigger jerk for the first opening then light, crisp pulls for proximate shots |
| Faddy revolvers include the Ruger Redhawk and Smith & Wesson Model 629 |
