i have a problem with the adjustable rear sight on my kimber . its still under warranty, had the piece for less then two months and not 150 rounds through it. they say i have to send the slide to a third party repair shop that works under contract. kimber usa will not deal directly with Canadian customers. should i be worried. besides poor customer service ill also have to pay the shipping back and forth to Alberta for the repair. bought the gun at SHOOTERS CHOICE and they cant even bother to return my call about it. thinkin i might just buy new sight and have it installed locally.i got to get it shooting straight. any advice folks. thx
