I just picked up a GLOCK 30, used, but not too used. Looks like about 50 rounds, tops. The copper colored lube was still on the slide and trigger bar. It was dirty and not lubed other than the copper stuff, but I reversed that quick. I can't wait to shoot it-it's a "pre-ban" in MA so it's a great score. I had a MA compliant G21, but foolishly sold it to fund another project. I won't make that mistake again. Any words of advice? How about carry ammo? Any 230 gr. HP?
