I think HK pioneered the concept of the MDP with the USP. It's a larger than standard duty with enhanced range and mission capability. For HD A light and laser make effective hits almost too easy. Add a Red Dot and you are in Unlimited Class IPSC IDPA territory which means you can hit faster, easier and further. A hand PDW more than a sidearm. Now we are seeing Rails and Optic Ready as factory standard 1-200yds with a handgun isn't crazy talk any more. Add 357sig, 10mm and 460 Roland and now we are next level. Even in 9&45 these are a step beyond older Service Pistols. The Ruger American Competition is a perfect candidate. If they made a 6" threaded version you could even add hunting and a silencer to it's list of capabilities!!! This is my Poly 80/Glock 22 with the 40 barrel installed and my Beretta.
