I have around 140 rounds of 1940's black tip ammo in M1 clips. I've heard this ammo has collector value. I've just been heating the barrel on the P17 with it. If anyone wants to trade it shell for shell with fresh ammo, I am more than happy to trade with you. Or sell it for $12 for 20 rounds so I can go to wal-mart and buy some new ammo. I'll even send the M1 clips and the emptys if you want them. I'm not a collector, just shooter and gladly help a collector out if you want it. :-)
