my first was Margolin, some 30 years ago. I joined pistol shooting league of sort, or how russians called it "section". Coach first checked all wannabee's hold and chose a few better ones ( I was one of those chosen). Then we were dry firing till we were blue in our faces. I think it was almost a month before we got to shoot pistols. Then coach implemented 3p rimfire rifle discipline, in his sick mind that was supposed to make better overall shooters. And I think it did. Oh, by the way, if some of us kids did something wrong, like accidental pointing the gun in a wrong direction or carrying in other than barrel down positon - he would kick that poor bugger right out. Oh and a lot of pneumatic rifle shooting too. How was that supposed to make us better at pistol I don't know. Anyways, Margolin still brings warm smile to my face.
