I've had Sig replace two guns over the years. Both for frame finishing issues (obvious machining marks). No hassle and very fast turnaround. They even let me pick any other gun/rifle within the same MSRP. Cost me nothing except FFL fee. I was pretty amazed. Anyhow, Sig puts their name on many things, but I would never buy anything other than an actual firearm from them. Their optics and other accessories are Sig-stamped garbage.
