I have a S&W 659 that I bought new sometime in the mid eighties. When I bought it I maybe put 30 rounds through and recently shot another 50 so it’s shot less than 100 rounds altogether. I recently obtained a CCW permit. I will never carry on a regular basis but I make frequent trips to the coast, mostly at night. The ability to legally carry when driving at night, stopping at rest areas for a break or nap has been much less nerve racking with my security blanket. I only need one pistol and have thought about getting a Sigma to replace the 659. I chose the Sigma because I don’t have the money for one of the more expensive autos and it’s a S&W. The weight of the 659 doesn’t bother me and it fits in an inside the pants waistband holster fine. My only worry is that it being a 2nd generation Smith will I be able to get parts or fixed if needed. After this long-winded explanation my question to those on this form with way more experience is, if weight and concealability aren’t a factor which of these two autos would you consider more durable and dependable.
