Re: What 9mm ammo do you prefer for defense and for practice?
Welcome to TFF, Radio!
Like you, I like a 9mm as a home-defense pistol and it is a really excellent target weapon also. Ammo is pretty cheap and it is extremely accurate. As for ammo, I generally shoot Winchester "White Box" 115 grainers for target, or the Independence brand, which is actually loaded by Federal. Both are hardball and both work quite well in my pistols. If you keep your eyes open though, you can sometimes find other brands on sale at Cheaper-Than-Dirt or Sportsman's Guide along with several other places online. Sometimes you will also see surplus NATO 9mm for sale which is 124 grain and works quite well too.
As for "serious" ammo, I prefer Corbon 115 grain +Ps. Others may disagree with this, but the stats seem to support my choice. Another good load is the Federal HydraShok round in 125 grain loading. A third, and also good choice, is the Gold Dot load made by Speer. This is the duty load issued by many police departments nation-wide.
