One revolver that I regularly put in the rotation of various pocket guns I carry around the house is a Parkerized post 1972 Colt Agent, which is a variant of the light, alloy frame Colt Cobra, which in turn is a variant of the carbon steel frame Colt Detective Special. The fit and finish of the later Agents often was not very good, but their factory action and lockup were the same good quality you would find on any other Colt revolver. Sadly, Colt no longer makes any of the aforementioned revolvers.
Gun stores and the internet are full of “experts” on Colt revolvers. If you want to read the truth as to whether or not Colt revolvers are delicate or will readily lose their timing, click here to read what a REAL gunsmith, Grant Cunningham, has to say about it.
The original short grips on my Agent were far too small for my hand; there was no way I could shoot the revolver comfortably or accurately. I substituted a smooth set of walnut Cobra style grips, further enhanced by adding a Tyler T-Grip. This combination is still just a bit too small for my hand, but it is as big as I can go and still keep the revolver hidden in my pants pocket. A well-worn but ever-durable Kramer pocket holster is my preferred carry for the Colt Agent. A quality pocket holster will keep your gun positioned where you want it and protect the trigger from an itchy finger. Negligently lighting off a round in your trousers could profoundly alter your future.
Other than the grips, the only remedial action taken on my Agent was to remove the razor sharp edges from the hammer. My goodness, I wish I could find knives that held an edge so well! A person could have field dressed a moose with that hammer. It took a couple of hours of careful work with a diamond whetstone for me to make that hammer less than lethal.
My preferred practice load is Federal AE38K 130 grain FMJ, which has roughly the same recoil and point of aim as my preferred carry load, the standard pressure Federal P38M 125 Grain Nyclad hollowpoint.
