I don't own one, but had the chance to fire one at a productions test shoot. We put hundreds upon hundreds of rounds through it and it ran smooth. One minor hickup towards the end of the day, but this was attributed to the high volume of ammunition and never having cleaned it. Took her apart, cleaned with rag in seconds, ran like a champ after wards.
Smooth shooter, felt good, not too heavy and priced right. If you're looking to use it for upland, I'd say it's a winner.
