I have shot revolvers for a long time at targets and had a good time doing it. Well, I bought a Ruger SR9 and had it out today. I normally shoot one shot at a time but today I got a good grip on the gun and pulled the trigger twice. Now I know what a double tap is -- short trigger pull on the second round. AND I had no idea it was that accurate with the second shot. Do all pistols shoot this way or is it just the ones with the saftey built into the trigger?
