I haven't had a lot of experience with them, but...
They seem pretty proud of their inventory, pricewise. With the building renovations and all I imagine they would like to start earning some of their investment back.
Kind of disappointed in inventory vs floorspace. Maybe that will change in the future.
Their approach to gun cases seems a little different, having to go get someone to unlock a cabinet and then stand there watching you fondle your potential purchase... dealing over a counter top seems to make laying the firearm down easier than handing it back and forth.
Sales people seem friendly enough. Not enough experience to find out if they are willing to "deal" with regulars.
Nice facility, nice shooting range. Memberships to the indoor range seem a little steep. I don't care for shooting indoors anyway.
I have two other LGS' where I am known that I would have to drive past to go to MSC. With higher prices, relatively limited inventory and no established relationships, MSC is going to have a hard time earning my business.
In short, they are worth checking out. Is paying them a visit a reason to drive from Berne? Only if you're going to visit other shops in the area as well.
