Surely, you don't expect someone like me (on a gun forum )...to tell you when you have enough shotguns....I only have what I need, is what I tell my wife...( and she's way too nice to say "bull".....)..
In Over Unders....
5 Browning Citori XS Skeet models ...all 30" barrels ( 2 in 12ga, 1 in 20ga, 1 in 28ga and 1 in a .410 )...(always good to have a backup).
2 Browning Citori XT Trap models/both 32" barrels..12ga -one with a GraCoil.
4 Browning Citori Lighting models ..all 28" barrels...3 in 12ga, one 20ga
1 Browning BT-100 - single barrel Trap gun ..34"...12ga...
In semi-autos...
a Pair ...of Benelli Super Sport models...30" 12ga / 28" 20ga...
In pump guns....
a Pair of Browning BPS pumps ...28" 12ga and 20ga....
and a bolt action WesternField - 3 shot ...16ga ....
--------------------------------------
so I guess its 17 ...unless I'm forgetting something...
( and I visit my local, used gun store, at least twice a month .....just in case he has something I can't live without.....)
I know I'm a little light on both 28ga and .410's.....
