Niche slider frame

[Carlito[]

Got one on a trilogy pump. Had it for a few years. It's starting to bind and not let the bolt catch. I've polished the plates but still no luck. Other than replacing the guts is there anything else I should look at?

When you say it’s starting to bind, what exactly do you mean? Is the trigger sticking back after being pulled? Also, which version do you have? Does it have a t slot rail or no?

It’s probably just the trigger return spring. Have you tried pulling it apart and giving it a good cleaning.

Need more info on what it’s doing exactly.

It's starting to bind and not let the bolt catch.

I would assume its the hammer that is not catching?
Have you adjusted the hammer lug?

also picture would help.
Have you remove the frame and check if the sear work well?

Well if it has the side to side adjustment screws or the travel front and back, up and down , try resetting them, sounds like the return trigger plate spring though...

T slot Asa version

Trigger is sticking back.

Sear looks just fine.

There's a pin in the back of the trigger with an adjustment screw in the front. That must be the return. It moves freely but there isn't much travel.

Sear spring seems fine, but possibly getting weak?!?!?

Probably just swap the grip. Sliders are great when they are smooth but they are so prone to failure in my experience.
