I intend both holsters (obviously not at the same time) for use during long distance vacation driving. The Model SKR (aka “City Slicker”) I plan for carry under a jacket with my S&W 442 Airweight, while the Model SMZ (aka “Smertch”) is for carry under a shirt (when weather does not call for a jacket) with my lightweight Colt Agent (alloy frame version of the Colt Detective Special). NOTE: The SMZ works both under a jacket or under a shirt. Ordering both hoslters was a bit indulgent on my part. These revolvers and holsters are LIGHT WEIGHT; I choose to travel light whenever possible. NOTE: The SMZ also can be ordered for semi-auto pistols.
