Looks like one piston seal life factor is how clean the intake hole is underneath the piston chamber. A factory burr will chew up your seal quick. But with 200+ shots through my new P17 and still getting 405 fps I think my intake hole must be pretty smooth. That said, I still see folks mentioning replacing theirs. Is there an average life where I should plan to have a spare on hand?
Where do folks get their spares? I read one post that said a #117 was the right fit, and of course the hardware store did not carry that size. They had a #116 but I didn't know how much of a difference there was...?
Same question on the little breach seal - mine developed a nibble missing after an unseated pellet clipped it while shutting.

I've had mine for over 2 years. Used it fairly often. I haven't had to replace the seal yet. Shortly after I received it, I disassembled and cleaned all the factory lube out. I used an ultra fine lapping film and polished the inside of the chamber. Then re-lubed with a good white lithium grease. Every 2 to 3 months I strip and clean and re-lube. Great little HOSP killer, cheap and fun to shot!

+1 Did pretty much the same thing. Still shooting after 2 years, same o-rings.

I bought a spare set of Orings when I got my P17. Almost two years ago and they haven't moved from the cubbyhole in the dash of my F150.
Keep it clean and lubed. I use a smear of Superlube with PTFE and be very careful you seat your pellets in far enough. One protruding the least bit might just nick the breech seal.
