My friend has a early ruger KP-95
that he has owned for close to
8 years.He has put over 12,000
rounds thru it,it'll still put
10 round into 4" at 25 yards.
BTW the front and rear frame
rails are polymer and show very
little wear.If the pistol was
designed with polymer instead of
metal frame rails i wouldn't be
too worried about it.
