| I already have the JP yellow springs but still had some grit so I dove in and did some buffing and polishing on the contact points of my trigger. When I put it all back together it felt awesome. Smooth, crisp, and clean. Pulled the trigger probably 10 times to feel it out. After those 10 pulls it progressively got grittier. Now it feels just as gritty as before polishing. Any help? Thanks. |

Question comes down to what contact points, and did you polish what areas you did so much that to break through any heat treating?
On the system, most of the gritty feeling is going to come from the pins to the FCG pin channels foremost. Once these are polished (may required over size pins if the channels are in very rough state), then you can start setting trigger take up from at rest to contact to the the selector at safe (you want none), then re-time the disco to .001 free gap at the trigger at rest point, true the trigger and hammer primary sears for a perfect 90* with sharp edges, then reset the hammer sear for working min engagement to produce a glass break trigger pull. Also, depending on the amount of metal removed, may have to reheat treat the parts From here, you can use a standard hammer spring tweaked at the coils to set the desired trigger pull/break weight. |
