I'm with the 340 PD folks. Only a little over 11 ounces empty...when loaded with .357 Magnum 135 gr Speer Gold Dot short barrel rounds and with its Galco horsehide pocket holster, right at 16 ounces. Melts into your front pants pocket, and because it is so on obtrusive, you are more likely to actually carry it. I have a lot of choices, and this is the one I am most likely to have at any given time.
There are lots of choices out there, but as noted above, the Centennial style revolver is snag free, and sealed against pocket lint in the internals.
Best Regards, Les
