I have two, factory, 12rd XD40 mags that I no longer need. Each has had about 150 rounds fired with zero issues. I sold the pistol to a fellow in California, where 'high capacity mags' are illegal.
I have an XD Sub compact that those would fit. However there is a little plastic sleeve that goes around the 12rd mag so it extends the handle. The gun came w/ 1 9rd mag that fits flush with the handle and 1 12rd mag with the sleve that extends the handle to be the same size handle as a compact XD. Do these mags have the plastic sleeve or were they for a compact model?
