A frangible or exotic round may be legal in your area. I'd avoid the Federal Guard Dog line. A YouTuber posted a detailed T&E with Guard Dog 9mm(9mm Luger) rounds with - results.
Corbon PowRball or Glaser Silver type Safety Slugs may work. They feed & cycle well in most modern pistols.
MagSafe is a well made brand. It's produced in central Florida.
DRT is a little known frangible but they are well made. Avoid the ExtremeShock USA line. That firm is MIA & the quality is sub standard.
