After a bad experience with a smith and wesson M&P9c, I bought a 442 revolving needing something easily concealed. I went out and shot 100 round through it noticing that my grouping at 7 yards wasn't grouping at all. In fact out of 100 round, only 15 hit the 12 inch target, and of those 15, none at point of aim. I am an -okay- shot. I decided to clean it, and upon cleaning I noticed how -terrible- the crown and barrel looked. Here are pictures. What do you think? Would this be the cause do you think?
