14 round M&P Compact magazine

What model extension is it pictured that you modified?

Pearce +2 for the XD-9.

I also tried a Walther +2 for the PPQ (made by MecGar but not the same as the MecGar Optimum +2). It was just a little too short front to back, but gave a much better pink hook than the standard +2. It could be modified but I decided not to do it and instead sent a long email to Hyve Technologies pleading with them to make a M&P9C +2 similar to what they make for the G26.

I've run a couple of the Mec-gar extensions on my M&P 9c's for a few years now. One will not easily drop free, (I'm sure filing a little of the top would allow it, but it's a range mag so I don't care too much) the other one does.

They have both been 100% with at least 1000 rounds through the non drop free and probably double that in the one that does. The drop free one is now my carry spare mag. No issues with the spring as the compact and full size mags use the same spring, so there's plenty of spring pressure.
