Single Action pistols are easier to shoot accurately because most shooters' hands move while drawing back the hammer through the trigger in a DA firearm. Arguably, many handguns used in competitions are single action, and support the above argument. Also, SA pistols, unlike DA/SA, don't have to adjust between the DA first shot and SA remaining shots. Often, when a shooter shot a magazine's bullets to a target, the flier (a shot that deviates significantly from a group) would be the first shot. However, SA pistols tends to have fairly light trigger pulls, and sometimes gunsmiths, as well as owners, may lighten the trigger so much that it can be considered as legal liability. Typical "safe" trigger pulls are considered at around 5 pounds. Typical DA triggers is around 10 pounds, and pulling such trigger, as argued by some in court, requires intent. A "safe" trigger pull is crucial in court, for example, to defend a shooter in self-defence from a negligence suit.

I like the merge to trigger (firearms) because it explains single and double action in the context of each other. Friday (talk) 18:48, 28 April 2006 (UTC)[reply]

Wow, that was a quick comment. I already merged it as a no brainer, but neglected to give people the chance. The clear reason for the merge is that single-action triggers, along with the other mechanisms, are best explained in the context of what the other actions do.--Asams10 20:24, 28 April 2006 (UTC)[reply]
