But before I go wild with tungsten, I'd like to have hard data, and that's where I need help. Could someone with a Ruger PC Cabine put their slide onto a kitchen or postal scale and share the result? Not need to take a photo, I only need the number. To start off, currently the weights are: bolt - 13.5 oz, buffer - 5.6 oz, total - 1 lb 3 oz or 540 g. Thanks in advance. P.S. If folks with Kel-Tec SUB-2000 chime in, it would be welcome too. UPDATE: 23.0..23.4 oz for Ruger, or about 657 g. No SUB yet.
