Hi, to be honest if you liked the Sterling back in the day, then you'll really love them now. Multiude of upgrades have been made to an already excellent pump , like thruogh the pump dialer, vertical feeds, etc. I own a classic STP and am in the process of building another. I also own a Bud Sniper2, Prostock and Bushmaster. Check out Sterlings website or Facebook page, Mike Taitt is an excellent bloke and I'm sure they can help. We had a pump and pistols day recently and there where many sterlings old and new, all performed very well.
