My son shoots 12, 20, & 28 and we should have done tubes from the beginning. But when he started we had a 12 Citori, then I found a 20 Citori, and a few months later I ran across a really nice 28ga Beretta that had beautiful wood and bought it for myself. And like kids do ... he started shooting it and I haven't seen it since then. I have offered to do tubes but he likes the current setup and that's fine with me.
