to the forums from the Wiregrass, Justin! That is a S&W .38 Military & Police Hand Ejector model 1905, Change 4 from the late 1920s or early 1930s. Your gun has been refinished as indicated by the plated hammer and trigger. The grips that are on it are not original to the gun. If you take them off, we can tell if it is a round or square butt. If the action works smoothly and the timing and pushoff are good, there is no reason not to shoot it. You can use factory .38 S&W Special cartridges. WalMart sells white box target ammo that will work fine.
