Ok got this pistol tried it out. It shit couple times then wouldn't chamber next load. Come to find out the last bullet didn't fully eject from the barrel. Thank God I found that out before trying to make it shoot anyway. I lubed it. Haven't polished it. It keeps happening. Is this a normal for for this s&w. How can I fix it. Btw it's a s&w sd40 ve. Maybe it's the bullets. Someone help me.
