I have a couple of buddies who have had them. They tend not be be exactly "tack" drivers, but normally capable of shooting 3 shot groups at 100 yards around 1" in varmint calibers, sometimes a little better, sometimes a little worse. If that same ammo shoots well in other guns, your buddy may have a bad one. That does happen, from time to time.
Was the gun purchased in a new or used condition? From a private seller or from a dealer? Perhaps the bore has rusted ...... particularly if it was a used gun. A lot of these are carried as "truck guns". Which means they don't often get cleaned or lubed and can be subject to the rusting which takes place, sometimes quickly, from alternating heating and cooling cycles in the truck cab. That happens quite often in high humidity areas such as Ohio. In CO, the humidity is relatively low, so I don't know if it is as much of a problem out there.
