24 years [and counting] of full time uniformed LE here. I recommend the GP-100. I carry one off duty; it's a stainless 4" model, backed up with 2 speedloaders, and all of it disappears with an IWB rig and an un-tucked shirt. In our profession, which is currently dominated by Austrian plastic, I'm something of an anomaly...but I don't feel the least bit under-gunned. As Jeff Cooper said, "One is only out-gunned if one misses."
