the mags for the ruger P-95 also fit that carbine, in case you have one of those pistols.
I’ve got two P89s and one PC9. The P89s are big, ugly, loud and indestructable. with the hi-caps that’s thirty rds before reloading. The PC9 is cute.
There are only two PC9s on gunbroker at this point. One for $325, the other at $650. Six months ago you couldn’t find one for twice that. I’m tempted to pick them up as an investment.
