Mec-Gar Plus-4 Magazine Extension Set Features The Mec-Gar Plus-4 Magazine Extension Set is built around a durable polymer magazine extender that replaces the factory floorplate to add four rounds of extra capacity to compatible 9mm Luger magazines. A phosphate steel locking plate is included alongside the extender and that plate is heat-treated to resist wear from repeated insertions and removals. This set is engineered specifically for Mec-Gar made magazines for the Beretta 92 Taurus 92 and Sig Sauer P226 and it is not intended for use with most other magazine brands. The straightforward two-piece design lets the shooter upgrade their existing magazines without purchasing entirely new units.

Every component in the line is built from sophisticated materials and thoroughly quality tested to guarantee reliable uncompromised performance once installed. The polycarbonate extender resists the wear of daily use while keeping the overall magazine weight down making it a practical upgrade for both range and duty use. For shooters running Mec-Gar magazines in a Beretta 92 Taurus 92 or Sig Sauer P226 this Plus-4 set is a simple way to stretch magazine capacity without added bulk.
