I have liked the results I got with WSF with my 9mm so today I decided to give it a go with the 40. I shot 10 rounds of 180 gr with G35. No crono today. All shot freehand. At 25 feet. 4.7 gr Fully function gun. 3.5 group feels good best three 2.25 inch. 5.0 gr Fully function gun. 3.0 group favorite group best three 1.1 inch 5.5 gr Fully function gun. 2.5 group tighter but more felt recoil best three touching. 5.9 gr. Fully function gun. 2.5 group wow she sure does bark best three 1.5 inch. Looks like somewhere around 5.5 is going to be my sweet spot. Wanna kill these ads? We can help!
