That's unfortunate, especially for a "flagship store" as it's called... Last time I went to the store was for the Freedom Days, which was a blast (got to shoot the LMG and met Jerry Miculek at the Mosberg stand) and they must have been well coached to behave a bit better than normal. I held tight and spent only a few $100s then... The time before though, ouch!
I do like the fact that there are pretty much everything they make and more but for the run of the mill SIG, you're right, there are many good shops that would match or even best the prices. Milford Firearms has a very large selection of firearms, and GSIR in Hudson is my base camp, very good people, great selection of rentals and decent amount of lanes. It can be crowded some days when the hordes of excited teenage Massholes want to relive their Call of Duty exploits, but overall it's a very good range.
