I had two 320s one L/E comp with the W320C9 pre tension barrel 3 mags , night sights and a late build full size 320 in 9 . I got rid of the full size 320 9mm and kept the compact L/E 9mm with the carry frame so I can use my extra full size mags . Traded on a new G17 Gen 5 3 mags and glock night sights they hit a home run with the updates they did on the Glock , ran 100 rounds and this thing shoots good , no problems . I think Glock will still be top dog on the streets
