i hve so many 'old style' P250 mags, and i know i can chane the baseplates to fit the new 320's, but aside from TGS (shipping is incredible) where can i get the simple gen 2 baseplates to put on my old mag shell???? i have a new sig compact mag coming in from the mothership (can't believe i paid that much for it) and i have a base coming from TGS. gun show today had one P250 FS and no one had anything else. scarcer than hen's teeth!!
