Purchasing a 21 is not just buying another SxS; it is an investment not only in money, but shotgunning history. You don't have to baby a 21 and can shoot any loads you choose. Given proper care, it will outlast you and any BSS or Stevens 311 ever made.(I've had those too)They are not "fence posts" as some claim; 12 gauge 21's are not English game gun weight and were never meant to be. 16 and 20 gauge 21's are excellent upland guns. I've had and handled Parkers, Foxes, & Lefevers that were as heavy or heavier than a 12 gauge 21 and didn't handle as well.Given the fact around 30,000 total were produced in all gauges and grades from 1931 to the 1980's means they will always be of interest to collectors and shooters and will not lose value if taken care of. One well-known purveyor and advocate of English doubles routinely takes a 21 to Africa for bird shooting safaris. I warn you though....owning and shooting 21's is like eating potato chips; it's hard to stop with just one as evidenced by the photo. Good luck.
