I need to see if the R9 I just got needs new mag springs, the pup I've had(still have) had the old style mag springs and would shave a little brass. New mag springs solved that way back when. I haven't been to the range with pup #2 yet, I'm low on ammo and need to do load some but the 1050's making 45's right now. Always something!LOL With 5 mag's between the two guns I've got enough of those, just want to keep the ones I have running!
