Since this thread has mutated a bit to be more about customer service in the gun biz than just CSM, I'll add a little something I heard the other day at the range.
I was returning my friend's CSM 21 .410 barrel and he was sitting with a couple other guys. It turned out one of them was an owner of a pistol range and store/gunsmithing biz geared toward the combat pistol sports. He stressed the importance of customer service over and over and making the customer welcome, regardless of whether they are complete newbies or veteran competitors. This struck a cord with me as pistol shooting was once my biggest passion. It's possible, the single biggest reason I am shooting shotguns today is because the pistol community, in general, was an unwelcoming, clic. The business side of combat pistols was permeated with counter clerks that were more intent on furthering their own agendas or fantasizing about being a Bruce Willis movie character than helping you. The shooting clubs were not much better and some of the members were downright scary people.
BTW, the shotgun crowd, is THE most welcoming group of shooters of all the shooting sports, and the best bunch of people I've had the pleasure to be around.
