I haven't heard of them, but the website looks completely legit. However, that doesn't mean that the person you're dealing with is. Are you buying the gun from that store or from someone who claims to be connected with that store? If it's directly from the store I wouldn't be concerned, but if it's from a person I would email the store or something and try to confirm the person's connection with it. When it doubt you can always do a third party, which is guarenteed to be safe (
www.palmer-pursuit.com has the best third party prices I've seen and they are known by virtually everyone).
