re: Home/Self Defense Ammo for SW Shield 9

TAFJ,
There's no "single" answer as to your question, but there a large number of highly respected 9mm self defense loads. You're job is to find the one (or maybe 2) that you shoot the best and your gun likes the best. As already suggested, the above link has lots of good recommendations and observations; use it as your guide. You'll find the rest of the article enlightening as well. Pick one or two of the self defense loads that are highly recommended and obtainable then try them in your gun. The one(s) that you shoot the best and your gun handles the best should become YOUR load. Having said that, I shoot 124 gr Remington Golden Saber and 124 gr Speer Gold Dot in my 9mm.
