Mec-Gar Plus 4 Magazine Extension Set 9mm for Mec-Gar Beretta 92 Magazines

This is the 140mm Plus 4 kit for Mec-Gar Beretta 92 magazines. A polymer extender and a heat treated phosphate steel locking plate replace the factory floorplate and take an 18rd magazine to 22rd, which is the setup competition shooters use to reach a division capacity limit in one magazine instead of two.

Fitment is narrow and worth repeating: Mec-Gar magazines only, and it will not fit Beretta factory magazines. Mec-Gar builds the same magazine body for the Beretta 92 and 96, the Taurus 92 and the Sig Sauer P226, and dealers list the kit for all of them. Two limits to know - in 40 S&W it adds 2rd rather than 4rd, and it does not add capacity to dimpled magazines. Black polymer over a black phosphate plate, and the swap takes a punch and a few minutes at the bench.
