Sorry I don't ship the magazine +2 Adapter to customers with a billing or shipping address in states or jurisdictions that have magazine capacity laws. CZ P-09 or CZ P-10 C, CZ P-10 F FACTORY POLYMER MAGAZINE +2 BASE PAD (comes with the neCEssary l shaped locking plate) 545900000. Also fits the CZ P-07 magazines. It doesn't line up as well with the grip as the original CZ P-07 +2 adapter did. CZ stopped offering those. DOES NOT FIT THE CZ FACTORY FCZ 75B, CZ 75 COMPACT 10 ROUND MAGAZINES OR TACTICAL SPORT MAGAZINES. THE DIMPLE ON THE CZ P-10 C AND CZ 10 F 10 ROUND MAGAZINES PREVENT MORE THAN 10 ROUNDS FROM BEING LOADED. I have also been told they don't work with the cz p-10 S 10 round magazines. they do work with the cz p-10 s 12 round magazines. THE +2 ADAPTER REPLACES STOCK MAGAZINE BASE AND MAGAZINE INSERT/LOCKING PLATE. THE REAR OF THE +2 ADAPTERS L SHAPED LOCKING PLATE/MAGAZINE INSERT THAT COMES WITH THE +2 ADAPTER NEEDS TO BE INSTALLED ON THE REAR OUTSIDE OF THE MAGAZINE TUBE TO HOLD THE +2 ADAPTER ON.
They may work on other magazines. Generally these won't work on magazines with thin or metal floor plates. The +2 adapter is thicker and will prevent the magazine from locking into the magwell. They are wider than the Mec-Gar 2 adapters.
