Why Don't Other Guns Utilize the 1911 'Straight Back' Trigger?

[D-Man]

Why is the 1911 style gun the only one with the 'straight back' trigger pull? (Or if there are others that use this, let me know).

To me it seems to give the best trigger feel as opposed to the more common 'top hinged' design (or whatever the correct name for this is).

Is it that it's so 1911-specific that it can't be done in other designs?

 

[HammerBite]

Most of the hammer-fired pistols on the market are DA/SA. To operate the hammer in double-action mode you engage a notch in the bottom of the hammer and pull it forward, thereby rotating the hammer back. In order to get from a backward motion at the trigger to a forward motion at the hammer you need a pivoted lever somewhere; it might as well be the trigger. A linear motion trigger is ill-suited to the job.

 

[Technosavant]

Sliding triggers, as wonderful as they are, don't produce enough movement to actuate a DA design. If they did, they would probably be decidedly less comfortable to use. The reason the 1911's trigger feels so wonderful is because of its single action nature.

By the same token...

Most single-action only autos do have straight-pull triggers: Colt 1903, S&W 945, Browning 1920, SIG P210...
