Yea Ive got a few extras for a couple of my pistols.
More mags make it easier when target shooting, training class, or comps.
XD9 came with 2, then I bought one of the accessory packs that has 3 mags in and mag carrier. The accessory pack was $50 I think, which is an awesome deal.
CZ SP-01 came with 2 19rd mags, I ordered 3 more 19s and one 16rounder just for the heck of it. They were expensive. The CZ is just a range gun, too heavy to carry, but I do plan on using it in a class this weekend if its not raining Sunday.
Kahr PM9 came with a 6rd and 7rd mag. I havent picked up any more for it. Kahrs wants $40each, I dont shoot it a lot and typically dont carry a reload.
Q: Why so many mags??
A: You gotta be ready when the "zombies" are wobbling up driveway. May not be time to reload mags. LOL
