CVA L & R LOCK INSTALL

[Mtman725]

So I picked up a L & R Lock RPL 01 for CVA, inletting and fitting went well, but I can't get the trigger pull, anywhere close to what I need. Called Tim at L & R, great guy, I cleaned up and polished the sear, cleaned and lube everything got it working and feeling right. I am convinced its the sear where it hits the two lever's, which I've polished and filed down, once installed it won't break the trigger, when it does it's got to be 12-15 pounds pull. I've compared the sear to the factory one depth look's right, polished and broke the edge. Input please. Its my frist one.

Here's the lock.

Did you tighten down the screws on your tumbler and sear? They are not supposed to be tight. How does the lock trip out of the gun, how much sear pressure?

I assume you blackened the trigger group and checked to see if it is binding on the stock, same for the lock.

The lock works just fine out of the stock, I'll double check the stock clearance. Found out not to over tighten them thru Tim, polishing the sear was needed there was a big 20, 30 ths. casting burr , that I worked down. Made a big difference in felt trigger pull,but out of the stock.

Something from The Gunsmith of Grenville County. The issue may be the location of the sear screw in relation to the pivot point of the trigger. A picture is worth a thousand words, hope this helps.

Sear is probably sitting to high and not getting hit by the trigger.
