I am condsidering purchasing a Hitachi DS18DMR cordlees drill but when I search for it sometimes I see the same model with a PS at the end(Hitachi DS18DMR PS). Does this mean there is a difference?

I can't answer the difference, but I found this a few days ago. You may want to look at it before you buy.

Hi,
Hitachi does not help much; the PS is in parentheses. See:
HITACHI Power Tools: Products > Cordless > 18-Volt > DS18DMR(PS) 18V Cordless 1/2" Driver Drill, 2.0Ah Batteries,
Peace,
