One reason and generally speaking, the older version is better than the new. For instance, earlier or pre-lock Marlin 39's. Older Contenders compared to the newer G2s. Older TC Hawken models (pre-stamped) compared to the newer ones. Older Remington Expresses better than newer ones. Older Belgium HPs compared to the new MKIIIs. Some folks prefer the Ruger MK=IIs over the MKIIIs and the beat goes on ....
Be Safe !!!
