Considerations & Trade-offs

  • 20 rounds per box is a relatively small quantity, so it may be better suited to carry practice or a limited supply than high-volume range sessions.
  • This load is described as a Silvertip Hollow Point, so it is intended for personal defense use rather than general-purpose target shooting.
  • The listed performance figures are specific to this 115 gr 9mm Luger load, so it is important to confirm they match your firearm’s needs and intended use.
  • Brass casing is a practical choice for many shooters, but the product data does not indicate whether this load is intended for reloaders or repeated reuse.
