What’s your setup? A dual rod undercocking kit with only one return spring in, along with a brass pump rod shim will drastically smooth out the pump stroke. As far as the trigger goes you can polish the sear and top of the trigger plate, but the difference is minimal. If you’re using the stock silver main spring and your TPC is near the front of the adjustment, you can swap to a lighter main (blue) and crank the TPC in just enough to get to velocity. If you can’t get to velocity with the blue spring you’d have to lighten the valve spring. Springing the gun as light as possible will improve the trigger weight, but may cost you a bit of efficiency
