I just purchased a H&K 45 C. The weapon is D/A - S/A. I don't need a safety. I am left handed. I would like to install a Decock Lever only on the right side of weapon. I can purchase the Decock lever at H&K Parts. What I cant find is the " HK Variant 3+4 Detent Plate" to complete the conversion. Would any members know what company may have these in stock or would any members possibly have one for sale ???? Thank you in advance.
