The 10 round mags aren't standard; those have a special floor plate that restricts capacity. The standard-capacity mags are 13 and 15 rounds.

Under normal circumstances the limited-capacity mags have relatively low demand and are easier to find than the standard-capacity mags. But now with more states limiting magazine capacity, those 10 round mags are hard to get also.

A quick check of major sites like Brownells and Midway USA shows they're out of both standard- and limited-capacity SIG mags but they have aftermarket ones in stock. You can find factory SIG mags at sites like eBay and Gunbroker but they're going to be more expensive.

For just range and practice the aftermarket mags will do just fine. But for self-defense I'd use the factory mags. If you don't want to pay a premium from eBay or Gunbroker, you might just want to find a site that will let you back-order them (I think Brownells will). Or you might just get lucky and find someone who has them in stock.
