I recently switched my duty pistol to a P365 XMacro, and purchased three spare magazines. Well, the magazines that came are the ones for the legion, which have different baseplates with an aggressive texture, and I like them a lot; enough that I want to switch my other four magazines over to the same base plates.

Does anyone know where to get them? I figured I would call Sig on Monday, but if anyone has a resource for them, I'd appreciate it. Thanks!

I think the base pads for the Sig Legion mags are made by the HENNING Group:

Just got ahold of Sig, and they confirmed that they are made by Henning. Called Henning, and they said that they can't sell the Legion ones, but can sell the regular ones to me, so I just ordered them.

Thank you

Proven has them at $50, $46 at 3 or more.

Sig has them too just in case.

I like the Legion mags too for that extra little lip at the front.  If you are going to buy a bunch of mags, additional grip modules, etc. it is worth doing the math on Sig Connect for the savings.  

Curious on what duty holster you went with?

I did the same and then came quickly from western Co.

changed all the 17 rounders and now have every color for different ccw needs or training days.

I like the legion baseplates. I like these a lot too. Order if you need some simple swap and work with all the grips I have with magwells.

do you know if these fit the 10rn mags also?

Unsure about the regular 10 round magazines but the blocked ones can't take a baseplate. The neutered mags are cut short and have a large plastic block/baseplate to make up the size difference. That's at least every neutered P365 mag that I've seen/owned. They aren't like the P320 mags where they put a couple dimples in the mag at the 10 round mark. Some gun stores will use normal mags and just install blockers. You might be able to have the store swap the baseplates before blocking the mags.
