I've got a 16-40 Limited and it runs great. I also have a Brazo open gun, a few springers, a colt, a glock and a few S&W's to compare it to. Honestly if it did not run I'd not own it.
I'd buy another one in a heart beat. I've got 25K rds through it and it has been very reliable. I've run major loads in it and resprung it and run minor loads for my kids to shoot it, no problems. The thing is a tack driver for my daughter with the minor loads.
Granted the finish is not on par with my Brazo, nor my springer from the custom shop, but I also paid 5-10 times more for those guns and waited 9 months for them.
