Great gun, but the one's I had had two issues...
(1) rust, and the gun was NOT abused, you HAD to clean it and oil it religiously, it simply didn't tolerate abuse.
(2) the vent rib on the barrel WILL bend if you tap it against a tree, drop it in the duck boat etc. It's an aluminum rib, a design flaw in my opinion.
Otherwise, I like the BPS.
Cheers
