For me, the frustration with CSMC is the inconsistency - you never know what are you going to get with their customer service. I bought an RBL from them last November - I had an issue with the rib soldering which they fixed quickly and effectively.
I went back to them this summer and bought a used Beretta 687 EELL. Upon seeing that the lever was left of center, I asked about the tightness of the action and was assured it was tight. My gunsmith then inspected the gun and assured me it was not tight. CSMC agreed to take the gun back and fix it in two weeks. The gun came back a month later, my gunsmith looked at it again, and informed me that no work had been done on the action. The gun is now back at CSMC for a second time (if I didn't love the gun so much, I would have sent it back for good).
I want to be a fan of theirs but they just don't make it easy.
