Before this decade...as in before 2002 ....??? ( damn, I'm getting old )...
It was the same then, as now, Browning Citori Over Under ...and my all around Citori, although I have several Citori's - field guns, Trap guns, Skeet guns, etc...my all around Citori - is a parallel comb gun, the Citori XS Skeet model, 30" barrels, with an adjustable comb...and I have that model in a 12ga, a 20ga, a 28ga and a .410....
My most versatile of the XS Skeet models -is my 12ga..../ but my favorite is the 28ga. Either one of these guns is at home on any clays field ( Skeet, Trap or Sporting Clays ...or 5 Stand ....and in the field for Quail, Grouse or even Pheasant.../ I'm too darn old to be chasing Chukar anymore..and too crabby to change guns now !
