Siesmic Sam . You mentioned Wolff but when I called them I was told that they did "not" make this spring . Midway has them back ordered for me and they do advertise them in 22lb . I figured I'd go direct to Wolff to get them sooner and that is when the guy I talked with said they didn't make them . This was just a week ago .
I can feel the slide hit with authority with the 3 standard springs received with the Witness Hunter. I'm using the marked "75AA KG 6 ,46" which I'm thinking is around 16 lbs. and the heaviest the pistol came with .
As I mentioned I'm using the 20lb. Wolff spring in my Witness 4 1/2" and I'm pretty sure it's to light . I ordered another 20lb. for the Witness Hunter 6" barrel not wanting to wait any longer for the 22lb. but still on back order .
Growing up in a sporting goods shop with a renowned gunsmith I've shot just about everything with a trigger attached . Started shooting competition at age 11 and shot professionally for Federal for several years and the "International Trap and Skeet Team" for the Army befor volunteering for Nam but all scatter guns . Pistols , while we sold them I never shot them . Reloaded for practice only as reloads were disallowed for competition and again scatter loads only . Over this period I've seen many mishaps with barrels exploding and even actions on some of the finest shotguns ever made even sending a few to the hospital .
I don't want to go half ass'ed into anything I do so must rely on others for their expertise .
I'm aware of lockup (my term) and do not have a chrono which I think is very much needed I'm sure to prove this out . Thanks
