Try GunBroker, another internet auction site, or stay vigilant on this forum. At times, members here put their Mk23s on sale. Brand new (never owned) Mk23's are now at premium these days because HK imports from Germany have thinned out. HK has made meeting military and LE contracts a priority, and us civvies get slim to none pickings. Things may get better in spring 2020 (or not). Good Luck!!
