I'm looking to pick up a CZ P10c, with an eye to using it for 3 Gun and carry. It comes with 15 round magazines, but evidently you can modify higher capacity CZ magazines from earlier handguns to work in the P10c. I'm looking for someone who can punch a hole in my existing magazines so they'll work and I won't violate any Colorado laws in acquiring extensions or new P9 magazines. The mod is pictured in the link below. I couldn't find a photo small enough to post.
