I have a first generation Striker, and this suggestion helped me a bunch. Not my original post....

To adjust trigger, I start at the front and adjust take-up. Next I adjust the spring tension and lighten it until the trigger pops, than add in about 1 turn. Next to the sear adjustment screw under the sear. Adjust in until trigger breaks, now out 1 full turn.

If you have a 1st gen, the rear roller needs to move freely, no corrosion. You may have to lube it and turn it unitl it rolls freely and make sure its nice and shiny on the outside.

Finally, cock it and bounce on bench on rear one time. If it pops, go and add a little spring tension.

A trigger job can be done, it involves polishing the sear face and the lever parrallel, and shiny.

Reassemble and don't torque screws too tightly, 30 inch pounds is plenty. Once snug, stop and try to cock it. If it binds, loosen 1/4 turn.

Apply a little fingernail polish to all set screws to secure once happy.
