And the Smith and Wesson Sigma series is one of the most popular handguns out there, doesn't make it the best, or good for that matter.
It's best part is generally when you see an AK vs AR debate its based on the AR guys wanting all the little do-dads and toys to go on their guns, and the AK guys boast they want a bigger is better round and they don't need bolt on toys.
Funny that Russia, started using a smaller caliber in their AKM rifles, and now they are doing just what we do with our AR15's, bolt on all kinds of goodies.
I guess imitation really is the biggest form of flattery.
