Re: front or rear trigger
15/04/08 02:05 AM

Below is the Hallowell website that shows photos of the lockwork for a bar action and back action sidelock as well as a photo of a two trigger gun which indicates the forward position of the common trigger pin, or common location if not a common, shared pin, around which the levers rotate.

http://www.hallowellco.com/boxlock.htm#Bar-Action

If someone knows how to post the actual photos that would be great since this is an interesting issue.

The blade of the rear trigger is further from the pin than the front trigger blade and perhaps this makes the rear trigger more mechanically advantaged, but then the length of the two triggers' levers as measured from pin to sear lever is equal.

Any engineer want to answer the question of whether the leverage is equal or advantaged for one or the other?

FWIW, the two locks show two sears each, one on each lock is engaged and the other on each lock is a secondary or safety sear designed to catch the tumbler, aka hammer,
from falling home in case the primary sear is knock out of engagement by cause other than the approporiate trigger being pulled. When the appropriate trigger is pulled, both sears are rotated so that the tumbler can fall freely.
