I agree that Ruger did a great job with the SR series of handguns. I carry the SR9C as my EDC, and I bought the full sized SR9 for range work when I go to places like Front Sight Firearms Training Institute. I just came back from a trip there and I have to confess that in the past I had never used the safety on my SR9... Well, Front Sight demanded that if the gun comes with a safety, I will use the safety while shooting there! Well this was my first time EVER using a manual thumb safety, and I have to say that this is one area that these SR's need some improvement. It was a steep learning curve for me, but the design of this specific safety was a definite hindrance. I am going to try to find a way to put an extended thumb safety on mine, but if I can't find a way to do that, I will probably end up selling both guns. The safety is just too hard to use. Other than that, Great Gun!
