Okay, I might have been a bit testy, and I'm sorry. Instead of getting up in arms I'll try to just stick to the facts.
We are not required to use drop leg holsters in my job. most of us like them because we work grip aquired (company policy). If you use such a holster your arm will be at your side instead of proped up in the funky chicken position. This does wonders for your funny bone, and improves draw time, too. It would not be my first choice as a cop, or in most security jobs, but since we do not wrestle with people and work grip aquired it is the perfect choice. Frankly, any holster up on your hip would indeed be more comfortable.
Weight? I have carried my M-15 90% of the time, but also carried my 6 inch Ruger GP-100. It's greater punch and longer sight radius were a comfort on rural routes. I stayed in practice and could place my shots at 100 yards if needs be. The weight was not a problem, and since the M-327 weighs less I figure it woulda been fine.
Bulk? Not really a problem as long as it is not heavy.
All that Electro-optical stuff? In the end you'll see that I only added a set of laser grips.
Shield driver's gun? No, we don't have shields, just vests, but I was pushing hard to get them.
Mall Ninjas: I hate Mall Ninjas and other Security Officers with rent-a-cop attitudes. I am a very avid shooter who likes to shoot for it's own sake. I also like cool guns. I do not think that gizmos will make me a better shot. I do not in any way, under any circumstances, think that the gun IS the job, nor do I want to play policeman with my toy gun. Playing cop is a quick way for a Security Officer to land his @** in hot water...and rightfully so.
I do shoot well enough to take full advantage of a top-notch sidearm. Frankly I could do my (former) job with any reliable gun of adequate chambering. Hell, a Tokarev with a 9mm barrel in it would do the job ok.
But like most of you I like nice guns, and if I can carry one at work: GREAT! Did you know anyone who carried a Colt Python back in their heyday? Could the Python do the job better than an M-19 or M-66? No. Were they cool? Heck yeah!
Lacking the ability to carry my new gun at my new job, I'll likely just get an XD or a Glock, or if they will allow a 1911 (turns out .45s are approved) I might go that road. Of course there are .45 wheelguns, too....
....I dunno: we'll see. An XD-.45 seems to be the frontrunner at this time.
