Shredder:
I have the exact same model as you.
I highly doubt it'll need service. About the only commonality between my friend's experience and mine is that neither of us cleaned them prior to firing. They're different models, bought at different stores.
I'll chuckle even more if I get it ripped apart and find all sorts of factory-packed goo inside.
Maybe my emotional image of Browning quality outshines reality - but I figure the chances of two brand new guns both needing service, purchased in the same town, by friends, at different stores, is about 0.
I'm looking forward to not breaking it down and giving it a good cleaning, but also heading back out to see if that solves the problem.
