A few weeks ago I sent my S&W Sigma 9mm back to them to fix the trigger problem. Problem was I had no idea when it would fire or what it would hit. I got it back and went to the range and I thought I was using a different gun, I was really pleased. So, a few days later I went again, the trigger was nice & smooth but I couldn't hit the broad side of a barn. I was using "Sellier & Bellot", 9mm Luger 7,5 g, 115 grains ammo, so I thought I would try some Winchester 0mm Luger 115 gr FMJ and at 25 Feet they were all in the black.
I just inventoried my ammo and besides the 9mm I also have some of their .380. Cost wise I've got over &100 worth of useless ammo in my opinion.
What do you guys think I should do? Being new to handguns I have no idea what to do. Help.
