Well ok ---- I would say don't buy it ..../ but I don't have any personal experience with the gun either.
I think its one of those guns that might hold up / then again it might not. You don't really know how many MIM parts are in it ...how good the steel is, etc.
Personally, if you want a long term pump gun - the Browning BPS is about as good as it gets in my opinion for around $ 525 for the Hunter model. I know the Browning BPS Hunter models - will give you a solid 30+ yrs of service / because I have 2 of them - one in 12ga and one in 20ga ....that look and operate almost as good as they did when they were new in the 1970's.
There are a lot of good pump guns on the market - Rem 870 Wingmasters, Benelli Novas, Browning BPS ....but I hope the gun works out for you. Put 500 shells thru it and give us a range report please !
