When you want a firearm that you know will not let you down while performing an arrest, serving a high risk warrant, or doing an entry or SWAT / SRT deployment it really doesn't matter how pretty the firearm. I've carried S&W, Colt, H&K, Steyr, Remington, Glock, and more on and off the job, (both handgun and long gun), starting more than 35 years ago.
For my money, a S&W J frame for walking around in my (current) somewhat rural environs...and a Glock anytime I step into a vehicle to head to town or further abroad. A shotgun and an AR on call. And of course a Spydie in my pocket. (The hardest part is figuring out which Spydie on any given day.)
