I just finished "The Trouble Busters". There's a very good fight between Freddie Woods and Kate Gilgore. They are are rival saloonkeepers and Freddie is also the mayor (and later marries the hero Dusty Fog). The confrontation builds up over several chapters and culminates in a showdown behind locked doors in Freddie's saloon, with their saloon girls also getting in on the act in an overall brawl (no men in the saloon). Freddie and Kate keep getting separated so they go into Freddie's office, lock the door, pause for a drink, and then continue their lengthy battle.
I'm now reading "Slip Gun". This also has a very good fight between Wil Jeffreys and Lily Shivers. Wil is the mayor and Lily is the saloonkeeper. Their rivalry goes back to childhood and there is a very nice build up to the fight in previous chapters. They finally agree to fight topless in Lily's room where there is only a bed. The other furniture has been conveniently moved to the hallway for redecorating. Lily locks the door and they have a sexy, long battle. This fight is now one of my favorites.
I now have 45 of his westerns - and I've just ordered 3 more. I've read 25 so far. Only 3 do not have a catfight, but they still have strong female good and bad characters and they are good stories.
I'm not a fan of female ring wrestling, mud wrestling or boxing; I prefer the different scenario fights with good buildups. Lengthy, even battles between attractive, well-built women, starting out topless, or becoming topless or nude as the fight progresses. These are the type of fights I'm looking for in JT's books. The 2 books I described above are just that.
