Not for 15 round mags... - Mec-Gar Plus1 Sig Sauer P226 Mags Basepad/Spring/Follower Conversion Kit

These are made for the Mec Gar 18 round Sig P226 9mm magazines; NOT for the 15 round magazines that the previous reviewer talked about. Be careful when buying upgrade parts. To be fair, Optics Planet was not clear in the item description as to what mags this kit would work for.

Buyer beware, as always.
