Here's a funny, but true story. Several months ago I was in my local gun shop, just for a friendly visit and catch-up. The shop-keep knows me well and knows my taste and always delights in showing me the latest the he knows will turn my crank. I'd barely got through the door when he pulled a firearm off the rack, opened the bolt and handed it to me saying "I know you're going to like this". It was a M70 feather-weight that had been custom tailored into a take-down switch barrel in .270 and 9.3x62. It was all extremely well done, tight and in excellent condition. I was then prompted to try the trigger, which I did. I then firmly informed the keep that this gun is not safe. He laughed and agreed that the trigger was light. NO, the trigger is not light, this gun is not safe, I replied. Several repeats of the same statement seemed to have little input until I passed the rifle back top him and instructed him to cock it and hit the butt on the floor. When he did that the audible sound of the firing pin falling was deafening. The shop keep was quite shocked and red-faced and put the rifle straight back up on the shelf with a new tag in the trigger guard saying "NOT SAFE".
