Walther Q4 SF. At 41 ounces it’s extremely heavy for a pistol with a 4 in barrel and its grip is very wide. I put thin Lok Grips on mine and that made the grip more bearable, but the weight was still too much and I sold it. It was a great shooter but it made my hands hurt. Eventually I picked up a Walther Q5 Match SF. Same weight, but 5 in barrel made all the difference. It’s a guided missile launcher and I can shoot it all day long.
