I own the following .38/.357 rifles/carbines:
A Browning B92 with 20" barrel
A Rossi '92 with 16" barrel
A Rossi '92 with 20" barrel
A Beretta Gold Rush (pump action) with 20" barrel
A Miroku/Winchester 1873 with 20" barrel
As you can see I own a few and not a Marlin in the bunch. I've owned Marlins in the past and just never cared for them....but I have no intention of mounting a scope or other optical sight on any pistol cartridge carbine or rifle. If I did I'd own a Marlin.
Of the bunch, the Browning B92 is the slickest and IMHO the best '92 ever made, including the old original Winchesters. It's closely followed by the Miroku/Winchester '73. The Browning's have been discontinued for years and finding a slick one will set you back $800-1,000. The '73's are available at $1,100 plus. Miroku/Winchester also makes a '92 in .38/.357.
The Beretta is discontinued but you can still find them for under $1,000, but be warned...getting one to run right can be difficult and expensive. But once you get it running right there's not a lever gun that can compete with one for fast shooting.
IMHO the Rossi guns are the best bang for the buck, unless you want to mount optics. People cuss the bolt mounted safeties on the Rossi's and the tang mounted ones on the Miroku/Winchesters, and I admit I don't like 'em period. But they're head and shoulders better than those abomination receiver buttons the late Winchesters and Marlins have. They're also easy to remove.
Of my Rossi's I have an earlier model with no safety and an newer BrazTech/Taurus model that came with one (it's gone now). I guess the first ones that came out after Taurus bought Rossi out were left overs and were kinda rough. I have two of the Taurus guns, another '92 .44 mag with a 24" barrel, and they were slicker out of the box than any of the older Rossi guns I ever owned or handled. A visit to
Rossi 92 Specialist, Nate Kiowa Jones a.k.a. Steve Young - Professional Gunsmith for his DVD and enhancement kit will slick up any of the Rossi guns to run like a Singer sewing machine or you can send them to him, let him do the work and really be impressed at smooth.
All of these guns can be finicky on cartridge OAL, so you may have to play a little with that if you reload. Also some of them don't feed .38's real well. Cowboy action shooter's usually have their guns set up to feed .38's reliably because that's all they usually shoot.
Another gun that hasn't been mentioned is the Henry Big Boy. I don't have one, but have shot several and found them to be very slick actioned and accurate. My wife's wanting one to go with her Golden Boy .22 for CAS so I figure there will be one in the safe before too long, I just don't care for not having a receiver mounted loading gate.
Hope this helps.
