Considerations & Trade-offs
- Its compact size supports easier carry, but the 4.32" barrel and 24-round magazine make it a larger package than many ultra-compact pistols.
- The threaded 1/2x28 barrel is ready for compatible accessories, but it also adds a feature set that may be unnecessary for users who do not plan to use them.
- The 5.5 to 7.5 lb trigger pull range may not suit shooters looking for a lighter or more uniform trigger feel.
- Interchangeable back straps help tailor grip fit, but the best setup depends on the shooter and may require some trial and adjustment.
