Anyone know of a reputable HK USP armorer/pistolsmith in SoCal?
Short version of the problem I need looked at: the hammer on my USP 45 occasionally drops back down to double action mode instead of staying locked back in single action mode after the slide is cycled(manually or during firing sequence)
thanks
