I started with a 4" 10-5. I now use a model 65-3 4" with packmeyer grippers on it. I use the comp 3's also, I was using the safariland holder but that was illegal. My holster is homemade ( cant find a left handed 4" k frame one anywhere in kydex) Now using the blade tech holder not as user friendly but legal. I have been loading 158 gr swc over 4 gr bullseye, just to knock down the steel.
