I live about 30 minutes from CSMC and have been there a couple of times, mostly because their gun room has a number of antique or high end guns that CSMC is selling in addition to their own products.
I don't expect to buy a CMSC made gun, my interests run mostly to vintage and antique British shotguns, so saying nice things about them online gets me nothing.
The only thing I've bought there was one of their canvas covered wood cases. I believe it was Lou who took the shotgun I wanted the case for and brought it out to have the case fitted to the shotgun. While we waited he chatted with me and another customer who was picking up a gun. About 15 minutes later, the employee brought the gun back. Since I was present, they deducted the shipping cost from the price I paid.
I'm not rich, I was probably dressed in very casually in shorts and a T-shirt and whether it was Lou or another employee, I was treated well.
I don't know why the experiences of people dealing with CMSC differ so much, I have a friend who went there planning on buying a CSMC and for whatever reason things didn't go well and he left without being a gun.
