What rifles does the factory 4 screw trigger fit?

[nsaqam]

I've never seen a 4 screw in real life but what actions were they made for?

Dont know exactly what all they will fit, but i have a 4screw on a la flat back and an intermediate flat back action

Anything that uses that style of trigger in a 110/10 series. Somewere around 1966-2000, before the accu-trigger, and the Stevens 200 can use it as well.

Thanks guys!

Any advantages to the four screw trigger?
What does that fourth screw do?

[keeki]

creep, travel, safety, and ones a keeper for the the pin that holds the trigger on

I've got one on my Stevens 200 LA and with a lot of patience and trial and error I've got it breaking right at 3lbs with a nice crisp feel.
I followed an article I found online about adjusting it.

The originals had a pivot pin with no head the 4th screw held in place. No advantage to the next ones that had a pin with a head and C clip. No screw needed to hold them in place, eliminating a machining process. The trigger still floated between the plates. Now if you combine the 4 screw with a headed pin You could in theory hold the trigger closer to one side if the hanger plate maybe giving it a more stable support.

Or you could shim it with feeler gauge stock.
