Hello everyone, I hope I am posting in the right place. I have a .38 special S&W model 10-5 with a 4" barrel, 6 shot cylender, square walnut handles, light scratches where the holster strap snapped down on it. Pistol works great, but having trouble with accuracy. I have been reading some threads and am assuming that it is not an original (.38 S&W special cartriage) since it does take a .38 special cartriage. Would like to know if it has been bored out to recieve the more traditional cartriage that is sold in most stores. The serial # is 2D93XXX. Does anyone know what year this gun was made? And what can I do to make it more accurate? Thanks in advance for your help.
