That’s exactly what I was afraid of. Not a problem though, I found a case of 200 PPU fmj for $130 before shipping. I’ll have to order that I reckon.Unfortunately you are going to have to order it online... I am afraid to shoot any of my GP11 as I can not replace it. PPU is one of the few that In know makes it still.
