Yeah because, after all, every modern army in the world is using lever actions and 8 round clips.
I give up - I bow to your "wisdom" - quail hunting shotguns are obviously a "match" for combat shotguns, which is why we see so many trap guns in use with the Border patrol and FBI. The conditions are exactly the same after all.
Failure to maintain your weapon is neglect on the part of the operator. Period. If you haven't learned that in 30 years of duck hunting, no wonder you like pump guns so much.
Have fun with your cap and ball weapons.
