I have a Stainless Steel guide rod for for a 4 inch XD pistol.
It comes with the rod, a 22# wolff spring. and 4 different washers.
The 22# spring was used on a .40 caliber model a slightly lower poundage spring would be better for a 9mm.
I would like to trade for a Stainless Steel, non captured guide rod for a Glock 19.
