Greetings, I live in NJ and can't have any mags that hold more than 15rnds. Being that Glock does not offer 15rnd mags for the G17, I'm curious if anyone has done a grip chop on a Gen 4 G17 to accept G19 mags? I currently have a Gen2 G17, Gen2 G19 and Gen3 G19 (along w/ a G26 and Gen4 G23). I am sold on the Gen4's and really really like the G17, but can't tolerate a 10rnd mag in the pistol. I'm fully aware of losing resale value and what not, but I do think the G17 has the perfect recoil signature. Some questions on the gip chop. Can you still use a grip plug? Can the hump placement be moved or removed? By doing the chop, does this limit me for IDPA and other competitive events?
