This was my first experience buying a firearm through Gunprime, and I couldn't be more pleased. The terrific price, super fast shipping, and ease of transaction using my favorite FFL dealer was top notch service. I'll be using Gunprime more in the future. I used the "email for price" option and immediately received an offer I could not refuse, even though I really was not in the market for another AR. I've fired a few rounds through the Sig Tread pistol just to zero a Sig red dot. I functioned well, arranging the brass in a neat little pile where it's supposed to. I like the fully ambidextrous controls. The trigger is smooth for mil spec. The adjustable KAK adjustable blade brace has just the right amount of contact, not too loose and not too stiff, and doesn't rattle. The handguard is slim and comfortable for me, I won't be changing it. The grip is a little too small to me, since I'm used to a variety different Magpul's, but it has good texturing like the P320's and P365's, so I'll probably leave it. I believe I can trust this Sig as much as any other brand for reliability. It will probably take up residence in my truck.
