Can somebody explain how TNW's semi sear works?
I see how the trigger gate hits the sear to release but I don't understand on how it's holding of the firing pin. TNW's set up is all in a horizontal holding and movement of the firing pin. And TNW's small sear spring doesn't look strong enough to hold, but some how it does, against TNW's massive firing pin spring.
I have worked on many sears and all have some surface on another pushing at each other untill one is moved and the other slides off. A good sear has a slight angle opposed to the release sear or release arm. If they were straight & polished you'll have a nice trigger pull but an unsafe firearm.
The surfaces are at different focal points. As in a revolver, the hammer with its sear wants to twist down in a rotating motion with the hammer hitting the firing pin or such. And the trigger sear lever is stopping that until the trigger pull slightly pushes up enough to slide off the hammer's sear then hammer rotates firing the gun.
Most of you here are probably aware of what I just tried to explained but with TNW's sear I haven't a clue.
