ISO Glock 21 "C" variant (aka "compensated", "G21-C", "G21C"). I have a 21C barrel NIB in need of a 21C slide. I am good with purchasing the whole pistol if the price (and location) are agreeable. Condition of wear/use is open, from well-owned to used_&_abused. Tell me what cha got... The worse possible outcome will max-out at "Thanks, but pass".
