870 trigger pin falls out

gotguns? · March 28, 2009, 10:12 PM

I gave my 870 a full blown cleaning last fall and got it out to shoot clays the other day. while shooting the front trigger pin fell out. What keeps this pin in place?

A little wire spring in the trigger group. Check the pin: some of them only have one groove around the pin, and they must be inserted the right wat so the spring catches the groove.

It does have a notch on both ends of the pin. Could that spring have fell out easily or is it possibly just not in the right position?

there is 2 different diameter pins. obviously the larger will not fit in the smaller receiver hole,but the smaller pin will fit into the larger receiver hole. and fall right out. what is most likely the problem is the spring in the trigger group that is around the hole for the pin, is stretched or broken. you can get replacement trigger group pins that "don't walk out". removing,installing, removing, installing. repeatedly will loosen the springs or break them.

Scattergun Bob would most likely know more on this trouble. he's most likely torn apart more that i can count on my fingers and my toes

Take a look at the diagram at http://www.urban-armory.com/diagrams/rem870.htm , specifically Part Number 70, which is hard to see in this drawing. That's what you're missing- the Front Trigger Plate Pin Detent Spring. It's sort of a little C clip that keeps the pin in place.

The name is bigger than the part...

You can likely get it from Brownells, or straight from Remington.

I solved this problem by using anti walk pins from Brownels
