I have two model 18's and Model 17-4 with 8 3/8 barrel that shoots like a laser beam, a Model k22 and a 6 inch model 617 no dash. My favorite range shooter is the K22 6 inch and my favorite carry 22 is a Model 18-3. The 617 with 6 inch barrel is a great gun but the balance of the K22 6 inch feels better to me in my hand.

Hope this helps.
