modify 25 rd cz 512 mag for cz457

[AlexYoooooo]

cz512 mags fits in cz457's mag well, but you probably experienced what I did, the mag jams almost every single round, and even it does chamber, the chamber opening will scrape down a chunk of lead
cause of this is cz512 mag's lip is slightly longer and held the bullet nose slightly lower than cz457/455 mag
solution is simply to file the lip back by ~1/16" (red area)and the bullet nose will tip up enough to go straight into the chamber, have fun with 25rd repeater

None of my mags have issues in any of my CZ's. 452,455,457, and 512. They all seem to work flawlessly.

I think its model-dependent, most of the people I know with MTR has trouble with feeding from banana mag
