Interesting thread.
My evolution parallels the majority of posters and I have tried to balance small, thin, and light with shoot able and reliable.
I am a big guy and when I was young I felt the need to carry big guns.
I started with a Beretta 92 and decided to move up to a 45.
I carried a S&W 645 for a while, it was a very accurate reliable gun.
I decided I needed a shorter barrel and carried a S&W 4567 for a while.
I found I could carry the above guns well with good leather. The Milt Sparks Executive worked well for me for all 3 guns.
I fell in love with a Browning Hi-Power and carried it for a while. I still really like this gun. Just after I started carrying the Browning I moved to Waco, TX. I decided smaller, lighter and stainless was the way to go.
I carried a Ruger SP101 for several years. I still carry this gun at times.
I have always been more comfortable with autos and soon I found myself carrying a S&W CS45. It is a great gun also.
I then discovered the Kahr K9.
This is my current carry gun. I have carried the Kahr for a little more than 3 years now and I am very pleased with it.
I have shot a defensive handgun course with it. My last conceal carry renewal course and a night shooting course. I have a little over 4000 rounds through the gun and I am really impressed with its reliability, concealability, comfort during carry and shoot ability.
I must say if you shoot about 1000 rounds over 3 days with a gun that small it can make your hand sore and give you blisters, but I was impressed that the gun could take that level of service.
