A buddy and I used to go to Bass Pro a lot of Friday nights (might have been why we were single) and one of the old guys behind the gun counter always told us that "You boys need a semi-auto shotgun. Those pumps are bad news, because sometimes you forget to pump."
We used to laugh at him, we both exclusively shot pumps and never imagined we'd ever forget to pump the action after firing. But then just last week I was shooting clays with my brother, who only owns an 870, and he kept missing doubles because, you guessed it, he kept forgetting to pump. Even worse was we went on a pheasant hunt on Friday, and he never got off any follow-up shots because he wasn't moving that action!
So maybe that old timer's advice wasn't actually that bad.
In other news, I've learned to ignore the "I carry a .45 because they don't make a .46" guys. In the grand scheme of things, the difference between a 9mm, .40 S&W, and .45 ACP is negligible when you're talking hollow points.
