Does it hurt my pump shotgun to stay loaded with 3 round in the mag when it holds 5 rounds?

No, load her up all the way you'll he fine. The spring won't loose its tensile pressure and even with 5 you'll still be able to push it in a little.

I keep a 500 loaded with five rounds of American made 2-3/4" 12 ga. I convinced myself it is not a problem especially as it is capable of holding five 3" American made shells!
