EVEN BETTER!

Review by Richard B. on 30 Mar 2025 review stating EVEN BETTER!
The backstrap is awesome but adding this magwell just turns it up to 11! The backstrap and magwell should be sold as a combo. I dig how the magwell really sits super tight and the attachment point is beyond rock solid. Mag reloads are smooth and intuitive with how well thoughtout the design is and the overall look is just killer with a great finish.

Great 20rd!

Review by Ty on 29 Mar 2025 review stating Great 20rd!
Feed great, solid build quality, and compact yet 20rds. Great for a backpack setup. Sit about flush with the hand grip vs the 30rds that extend past it
