I owned one for a year when they first became available in the late 80's
What every one has said here was true, wonderful gun, to me the Heat problem was a NON issue.
The reasion that I got rid of it was the basic operation of the pistol.
I had and have been shooting for a long time and my grip is not that firm, it was the way a professional (rode the trains with Harry Truman)
showed me when I was starting out in the late 70's.
The problem was that when I pulled it from a holster and tried to shoot fast not every time would it go off.
It was a problem with me, NOT the gun, I wasnt gripping it hard enough to cock the gun. That scared me, at the time I was doing some work that might require quick action and I needed somthing that I could trust 100%, the gun and my operation and it was lacking.
I still think that the overall desighn is THE best 9mm ever built if it works for you, it just diddnt for me.
