My S & W Mod 5946 served me faithfully for 20yrs without firing a shot on duty.  The Kahr K9 was my backup or off duty and served me well too.  I was little reluctant to buy the Kahr due to owners relationship to “Moon” religious sect.  But I must admit it is a very good shooter.  When I was in the Police Academy, I had to choose between S & W, Glock 19 and Sig P226. And I went with S & W due to the fact it fit my hand perfectly. Note the S & W is double action only.  Now the Kahr is my EDC with 8 rounds of 124 grain Speer +P 9mm JHP.  Last couple of the photos are for size comparison.
