Considerations & Trade-offs

  • Holds two magazines, so it adds bulk and weight compared with a single-mag carrier.
  • The curved profile is designed to sit closer to the waistline, but it still depends on belt fit and carry setup for comfort.
  • Magazine fit is listed for 9mm/.40 Cal/.45 Cal/10mm/357 Sig, so compatibility should be checked against the specific magazine style being carried.
  • The adjustable belt-clip hook and included belt loops offer mounting options, but that also means setup may take a little trial and adjustment to dial in securely.
