I frequently carry a 337 Ti on the ankle or in a pocket. The reasons are the same as already stated...Reasonable power for size and weight. Its reliable and not too sensitive to ammunition type or bullet shape. It's simple to operate and can be operated in less than ideal positions. Contact distances are not a problem. I started out in law enforcement with a M10 and carried revolvers on and off duty for a good many years. I don't exclusively carry revolvers but I prefer the J Frame to the little .32/.380 autos.
