The flint was fixed to a swinging arm called the <i>cock</i>. Prior to firing, the cock was held rearward under spring tension. Pulling the <a href="/wiki/Trigger_(firearms)" title="Trigger (firearms)">trigger</a> allowed the cock to rotate forward at a speed sufficient to produce sparks when it struck the steel <a href="/wiki/Frizzen" title="Frizzen">frizzen</a>. This ignited a small priming charge in the external <a href="/wiki/Flash_pan" title="Flash pan">flash pan</a>, which in turn ignited the propellent charge in the <a href="/wiki/Breech_(firearms)" class="mw-redirect" title="Breech (firearms)">breech</a> through a connecting vent hole. The identification of percussion sensitive <a href="/wiki/Fulminate" title="Fulminate">fulminates</a> provided an alternative to spark ignition of the propellant. The <a href="/wiki/Percussion_lock" class="mw-redirect" title="Percussion lock">percussion lock</a> (also caplock) was adapted from the flintlock firing mechanism, with the <i>cock</i> being modified to strike a small cup-like cap containing percussive material. The cap was placed over an external <i>nipple</i>, which acts as an anvil and conduit to ignite the main propellant charge within the breech. In this use, the <i>cock</i> has come to be termed a <i>hammer</i>.<sup id="cite_ref-:3_5-0" class="reference"><a href="#cite_note-:3-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> </p> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:Caplock.gif" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/8/8b/Caplock.gif/220px-Caplock.gif" decoding="async" width="220" height="172" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/8/8b/Caplock.gif 1.5x" data-file-width="277" data-file-height="216" /></a><figcaption>All caplock mechanisms rely upon a <a class="mw-selflink selflink">hammer</a> impact.</figcaption></figure> <p><a href="/wiki/Samuel_Colt" title="Samuel Colt">Samuel Colt</a>'s <a href="/wiki/Colt_Paterson" title="Colt Paterson">Colt Paterson</a> revolver of 1836 used percussion caps.

Whereas the percussion cap in the caplock mechanism was external, the percussion cap in a self-contained cartridge is inside the breech.

Additionally, for those who carry their firearm as a personal defense weapon, there is the ever-present worry that an external hammer may catch on a loose article of clothing in an emergency situation, because the hammer protrudes at an angle from the rear of the weapon, and as the owner moves to quickly draw their weapon, the hammer may snag on clothing and cause the loss of seconds in a dangerous situation. Paul B. Weston, an authority on police weapons, called the external a "fish hook" that tended to snag clothing during a fast draw.<sup id="cite_ref-9" class="reference"><a href="#cite_note-9"><span class="cite-bracket">[</span>9<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Linear_hammer">Linear hammer</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Hammer_(firearms)&action=edit&section=3" title="Edit section: Linear hammer"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>A linear hammer is similar to but differs from a <a href="/wiki/Striker-fired" class="mw-redirect" title="Striker-fired">striker</a> in that the hammer is a separate component from the firing pin.<sup id="cite_ref-10" class="reference"><a href="#cite_note-10"><span class="cite-bracket">[</span>10<span class="cite-bracket">]</span></a></sup> When released, a linear hammer, under spring pressure, slides along the bore axis rather than pivoting around a pin placed perpendicular to the bore, as with the more common rotating hammer.
