Considerations & Trade-offs
- The 5.7x28mm chambering and 20-round capacity may be more than some users need for a compact handgun setup, so it’s worth matching the platform to your intended use.
- The slide cut supports most red dot optics, but optic compatibility still depends on the specific sight and mounting setup.
- The pistol ships with adjustable rear and photo-luminescent front sights, yet the co-witness arrangement means optic setup and sight picture should be considered together.
- At 25.2 oz with an 8.2" overall length, this is not the most minimal carry option, so size and weight may matter depending on how you plan to use it.
