The newer Ruger's with three digit SN Pre-fixes will not handle as stout of loads that the older Two digit pre-fix numbers will handle. However, the newer frames are trimmer and are well balanced. My advice is to Ruger over the import stuff. Do check out the older Rugers against the newer ones and make your decision.
You talkin’ Vaqueros or all of them?
Ruger now uses their medium frame on both Vaqueros and Blackhawks. The medium frame will have a three digit pre-fix in the serial number. I am not positive, but medium frames are offered in 44 special, 45 Colt, 45 ACP and 357 Mag. I don't know which frame is currently being used for the 41 Mag, 10MM, or 30 carbine.
The super Blackhawk frame is being used for 44 mag, 454 Casull and 480 Ruger.
Ruger Super Blackhawks are still a heavy frame.
