Hello MM. I have a PA Greener as well. IMO, very, very nice guns. I replaced the hammer springs and polished the chambers just a bit to make mine competition ready. My only complaint is the hardwood stock. I tried to find one with a walnut stock, and to buy a replacement walnut stock from PA but no luck. Seems to me a gun that nice (and expensive) deserves better than a hardwood stock.
I shot mine about a year and then discovered a Win. '87, so mine is now a safe queen, but I still do admire it. That Greener system built with the percision of the PA guns is to be admired. If I were still shooting it, I would probably have it restocked with nice wood.
Enjoy your!!
