Writing as B.B. Pelletier
Today’s report is written by blog reader New To Old Guns. We met at this year’s Pyramyd Air Cup, where he showed me the items you are about to see. I was impressed, and so was Val Gamerman, the president of Pyramyd Air. He gave his inventions to Val to take back to his office to evaluate, and he and I had already decided that a guest blog would be the right thing for everyone else. So, here we go!

3D printing to the rescue!
This report covers:
- The Sumatra magazine, the start of it all.
- What is plastic printing?
- How does the printer print?
- Early success: the clip holder
- Iteration is what makes this great!
- Follow on success: belt and gun mounts for the clip holders
- The power of 3D printing
- Other resolved issues with the Sumatra
The Sumatra magazine, the start of it all.
Around 2003, I purchased the Sumatra 2500. It was a beast of a gun compared to anything I’d owned before. I was immediately smitten. But, it wasn’t long after opening the box and starting to use it, I found the first design choice I disagreed with. The clip is little more than a cylinder with 6 slightly tapered tubes and a pair of spring-loaded bearings front and rear providing centering force. There is nothing holding the pellets in the clip! That’s great, in that there is nothing to deform the pellets as they’re loaded and shot, but not so great because you can’t preload clips for field carry. The pellets just fall right out of the clip!
