Other than the mechanical issues, there are a couple things I don't really like about the gun:
(1) The weight is significant. Especially by the time you add a couple toys.
(2) The sights don't flip down, I would have preferred that style so it would not interfere with my optic. I had to use a riser, which add more weight to a gun that's already heavy.
(3) The grip SUCKS! I don't know why you make a quality gun with a cheap plastic grip, and the worst part is, I have not been able to find a Hogue style replacement, or any replacement grip.
But as long as Sig fixes the issues, I'd buy the gun all over again. There is no recoil compared to a DI gun or any AR with a buffer spring. Even with the weight, it is very easy to to keep on target. With my red dot, I put 30 rounds in a 2 inch grouping at 30 yds shooting as fast as I could (even with the misfires lol).
Hopefully Sig will be quick to send it back, and maybe a couple goodies for the trouble.
