After pinching my palm for the last time pumping up my 1377, I went looking for an easier to grip option. I considered a wooden grip, but I wanted to keep the cost lower. At some point in my wandering I acquired a model of a Crosman Pump arm, and after making it more solid, I added a big bit to grab onto and this is the result. (I'd love to link to the original pump arm model, but apparently I only have the STL and haven't been able to turn it up. If anyone recognizes it and can point me to the original, it'd be much appreciated:)

Update: The original is here: https://www.youmagine.com/designs/crosman-1377-pump-arm

The pictured one had a little warping on the front end during printing, but I slapped it on there anyways, and at this point it's been used for a few hundred shots, so a few thousand pumps with no issues.
