I have a 2003 made Walther P22 that uses the serialed FCG. So this modular idea wasn’t Sig‘s, Umirex was way ahead of the curve on that. The Beretta APX also uses it, and is better than the Sig offering.Yea I was all about to yawn too. I thought "Oh great it's XD 2.0".
This is a completely different gun and it brings to the table the RDO system that doesn't use plates along with the Sig module modularity. I think it has a lot more appeal than S&W's new 5.7 and .22mag offerings. It'll sell if it doesn't have teething pains like Sig did.
