Dag Evert's "American Classic"

As mentioned on the forum, heres a picture I took some time back, with natural winter daylight.
A 2100, and a 1377, both guns have been recrowned, and had their trigger parts shimmed for play,
contact surfaces stoned, and trigger springs somewhat reduced within safe limits.
The 2100 has had its barrel shimmed with tape to remove play.
Both guns give great accuracy for the money if they are given good pellets!
The combination of pellets and guns in the picture represents something close to my boyhood dreams:-)

Response to Specific for 1377?

"don't really have anything holding the valve from forward movement except for the transfer port bucking"

Forgetting about the pump arm pivot? Most of the striker energy goes into cracking the valve.
And prior to cracking the forwards movement is resisted by the pump linkage.
The reaction force on the pivot pin in idle state is the pressure on the front side of the
check valve multiplied by piston area. This is the force the striker must overcome
to even start the valve body moving forwards.

Extra securing never hurts unless it's positioned badly. If the holes are aligned
so that the screw takes all the piston's force before the rear lip does, then you
could end up with a damaged screw that's hard to remove.
