I ran into some issues with a HSNM trigger I have installed. It has a hitch in the trigger pull, but I don't think it's the trigger, I think it's rubbing on the lower somewhere. Rather than try and spend some time diagnosing that right now, I'm trying to put a SSA into my kid's Service rifle for this season. I thought it was an SSA, but I think it's an SSA-E as it wont lift up my trigger weights.

Am I correct that these two triggers are the same, except for the springs? If I replace some of the springs I should be able to get to 4.5lbs? Can you tell me what color the disconnector and hammer spring color are for the SSA? I have a pile of spare parts and I may have some in my box of stuff.

TIA

Springs and break. The SSA-E is 1# lighter and has an icicle like break. The SSA has a carrot like break. The SSA-E also has a shorter reset I believe.

Yeah the SSA-E will not make weight (4.5lbs). I have a trigger weight and it will not lift it. My understanding was that I could put in an SSA spring kit on the disconnector and trigger and get to 4.5lbs. I'm not too concerned about the break as either the SSA or SSA-E will be fine. I just need it to make weight. I think they are a different color but I'm not sure.

I wish I could figure out why the HSNM had a hitch in the take up. I thought it may be rubbing on the Aero Prec. receiver but I could not see anything when I took it out.

Interesting. I always understood that the SSA trigger spring would bring the SSA-E to 4.5#. Sucks that it isn't working for you.

SSA: black trigger spring and blue disconnector spring

SSA-E: silver trigger and disconnector springs

If you talk to G they will take care of you.

Thanks everyone for the help. I robbed some spring from another trigger and they worked great this weekend.
