No this is not a comparison, me and my friend went to the range today. As you all may or may not know, i just got my G30sf this week and so did my friend. When he came over, i was cleaning mine before we left. He said "dude, you dont need to clean it, it will have no malfunctions...plus it has the copper grease". I said you still need to clean it because it is dirty from being in the warehouse. He wanted to bet a box of ammo that his brand new never been fired G21sf would work flawless straight out the box. Of course i took the bet and yes i won!! I wasnt sure of myself but sure indeed, at least five mags had FTF. We only load five at a time and after the third, it would jam up. Mine being clean worked great. I didnt think it would malfunction as much as it did. Has anyone ever seen this before?
