if your piranha isn't working for what ever reason (leaking,not shooting,ect) look here
. that was posted on pbn by a piranha tech that works for PMI. if that doesn't help than call 1-800-579-1633. that is PMI's tech support. they are very helpful.
if there is a specific part on your marker that is broke, lost, or missing for what ever reason then you want to e-mail PMI. there e-mail is email@example.com
. what you do when you e-mail them is you tell them what part you need and what your address is ect. here is a sample letter.
