They do not work with Stock Magazine base plates. They should work with some Magwell compatible base plate extensions. But we have not checked all brands/companies. They do NOT work with the New style TTI Extensions.
They are designed to work with our +2 or +6 extensions along with our the Low Pro and Med Pro Magbase plates.
Thank you for your patience as work on making the products that fit your gun.
