Considerations & Trade-offs

  • Its 7.2-inch overall length and 4.3-inch barrel place it in a compact carry format, which may require more attention to holster selection and concealment setup than a larger duty pistol.
  • The 1.1-inch overall width and 23.1-ounce weight are carry-friendly, but the pistol still includes features like a removable magwell and accessory rail that add versatility rather than absolute minimalism.
  • Interchangeable backstraps and the removable magwell offer useful fit and setup options, though they also mean the pistol may need some initial configuration to match personal preference.
  • Capacity varies by magazine at 21, 17, or 10 rounds, so the carried setup will depend on the magazine choice rather than a single fixed configuration.
