I had been carrying a Glock on duty for the last 5 years or so. Started looking at other systems, particularly the Springfield Armory xd45. Saw a used 4506 in a local gun store and bought it on impulse because it felt good. Took it to the range and was hooked. I lucked up and found a level 2 holster in a bargain bin at the local uniform place. Waiting on magazines and I'll be carrying it on duty. Definitely on over-looked gem.
