I currently have a PCR and a P-07 that I alternate carrying. I love both, and I'm perfectly happy with them as my carry guns. I'm now interested in buying a handgun more for fun and customization, like slide work, optic milling for an RMR, compensator, etc. From what I've seen the most common platform for this is Glock, but I'm also curious whether there's enough aftermarket support for me to go wild on a CZ pistol. So I'm also considering a P-10c or another P-07. So my main question is, if you were to go crazy customizing a handgun, which of the above 3 would you go with, or would you choose something else?
