I plan on having a navy/HC P-11 (if I can find one, if not Black/HC) by the time I get to 6000 rounds on my P3AT. That way I can ship it to them and get it all sweetened up (if they will do that of course), and still be covered.
I don't know about most rounds through the P-11. My brother has got to have close to 2500 in a P3AT at this point and there was a guy in the P-32 section that said he had basically 12-14,000 rounds through his daily carry P-32 and it was still ticking. Kind of impressive for these little buggers. I don't recall ever seeing a round count post in this forum though. I would be curious myself.
I can't talk myself, I only have 144 through my P3AT at the moment (saving up for a P-11, but the new version will probably be here by the time I have saved up

), but I plan to add another 100 to the total next week at the latest.
