Sorry I don't ship magazine extensions to states that have magazine capacity laws or customers with a billing address in states with magazine capacity laws: California, Colorado, Connecticut, Hawaii, New Jersey, Maryland, Massachusetts, New York, Washington DC and Cook County, Illinois. NOT TO BE USED TO ASSEMBLE MAGAZINES WITH A CAPACITY HIGHER THAN LEGAL IN YOUR JURISDICTION.
Mec-Gar plus 2 adapter and the special magazine insert needed to use them. The plus 2 adapter adds 2 extra rounds of capacity to the Mec-Gar magazines listed below. These are not the same plus 2 adapters used on the Mec-Gar Sig Pro, P228, P229 or P229-1 magazines and they won't work on those magazines. They also don't work on the standard Sig factory P226 (with metal base plate), P228, P229 or Sig Pro magazines or the CZ 75B 16 round or CZ 75 Compact magazines. THE REAR OF THE +2 ADAPTERS L SHAPED LOCKING PLATE/MAGAZINE INSERT NEEDS TO BE INSTALLED ON THE REAR OUTSIDE OF THE MAGAZINE TUBE TO HOLD THE +2 ADAPTER ON.

I have also had customers use these on the Springfield and Mec-Gar XD, S&W M&P 9mm, .40 and .357 Sig, Witness/Tanfoglio Small Frame (current Mec-Gar style), Canik 55 Compact 15 RD 9mm, Canik TP9 SA, Ruger SR9, CZ factory P-07 and CZ P-09 magazines.
They can also be used on the CZSP01 18 round factory magazines. When used on the CZSP01 18 round magazine you end up with a 20 round extended magazine.
