Sig is not out of business. They lost one distributor. It may have been the distributors idea or it may have been Sig's, who knows. It happens all the time in the retail world due to disagreements over pricing, advertising, etc. You can always get Sig stuff from a local hobby shop, direct from Sig or at other online retailers such as www.advantagehobby.com (Advantage Hobby is great by the way)

This has been discussed in a number of threads here on RCU.
