If you want a copy of a traditional English sidelock game gun, i.e. straight grip, double triggers, splinter forend, etc, a Spanish gun would probably be a better pick. But if your taste runs more toward a traditional American style such as a Model 21's typical configuration of pistol grip, single selective trigger, and semi-beavertail forend, not to mention quick and easy service, the CSM RBL is the better choice.
