I bought SN 356 in early 66. It was the only off duty gun I could afford back then. Still got it today. It is a very accurate and reliable weapon. It is still in its original box as I got a raise that year and bought a Chiefs Special. I recently bought a Charter .327 mag, 2.5" barrel and it is also a very good weapon. Bought it because I did not want to hazard a lot of cash on what might become a extinct caliber, guess no worries there now. It is POA/POI at 20 yards with 100 gr JHP American box loads. And it seems to pack a punch.
In my early Undercover I used 158 GR SWC ammo almost exclusively and it is still as tight as the day I bought it.
