I'm in.The freebe mods (just your labor) can make a huge improvement on this airgun.They usually benefit form re-crowning of the barrel.Polish the breech lead in.Pin the bolt end or at least turn /grind the cone to a pin.Port the valve and turn/file a waist in the proper place on the pop valve pin (firing pin to some)Find a slightly softer trigger spring (Ace hardware less than a buck) and insert an empty cal. 22 brass into the top end of it for a spring guide.Polish all contact points in the trigger group and on the hammer.Use small brass washers (ok, not totally freebe but under a buck) to shim the sear and trigger pivot pins and remove the slop.You can also swap the valve spring for the one you replaced in the trigger group. It is softer than the original valve spring and allows the valve to "pop" faster, thus getting the air down the barrel before the pellet leaves it.Replace the little metal transfer tube between the valve and breech with a "poly port." this is a very short piece of polyethylene, high pressure tubing usually used in ice makers. Getting it just the right length and shaping the ends right for a good seal takes a little fiddle faddle but it is worth the effort.All of this should cost less than 4 bucks and you will notice a substantial improvement in accuracy, especially when using heavier pellets.A pic of my favorite 1377 although it now sports a slightly longer barrel......
Okay. So, where are the instructions/pictures?

John: You are the first person to do every mod known to man to a 1377. Nice shooter you got there.
