I never had issue with my 30's or 36's, recoil and flip wasn't bothersome at all. Mine did have the 9 round mags so it was flush. I believe they were gen 3 or maybe before. I'd still have one but I kept selling/giving them to cops who wanted them.
Ironic on one of the 30's and officer was thinking about one so I let him take it to the dept range to try out. First mag, the recoil assembly came apart and tied the gun up. They brought it back in a baggy. I never had problems with any of my guns any place but at that range. I think it was cursed.
I just had to replace the recoil assembly provided for free and never had another issue.
