Vic - Could be, I'm not familiar with the mechanics of the Schwartz Safety system, but at first blush it looks similar. Hopefully, Sig's treatment of the firing pin safety will be better executed than Kimber's. If anyone has a diagram of the mechanics of the Schwartz Safety system, I'd be glad to compare/contrast the functions of the two.
A better safety would be akin to what Sig classic pistols have, which is like the Series 80 safety, where the firing pin block is disengaged by pressing the trigger. Send some pictures, I'd like to see what type of safety the Sig GSR have. If its a Schwartz-type safety like Kimber has...
So the Kimber is worse than the Colt Series 80 because it doesn't mess with the trigger pull?
