Question for ya all. I have a Kahr MK9 for summer carry, besides the fact that its 9mm and not something a bit larger I lOVE THIS GUN!! I haven't experenced problems like so many other Kahr owners have thankfully. Anyway my question is for any other Kahr owners that know anything about switching the factory guide rod for the stainless steel one. Any problems with doing this. I heard you may have to shorten the SS rod and file down some edges, If this is the case I think im gonna pass.
