Pugs,
Can I suggest that you leave the safety OFF at all times on your clay shooting gun and perhaps concentrate more on actually shooting the target, in particular if you ever intend to get into Competitions in ANY Discipline. If you can find a Gunsmith to show and explain the workings of the safety catch on a shotgun, you will see that it ONLY locks the trigger and does not prevent the hammers from hitting the firing pins. The reason for the non auto safe on 'Competition' or clay shooting guns, is to prevent it inadvertently being left ON when shooting. If the safe is permanently OFF, it avoids this, which, in Competition is called as a 'LOSS' and that could be the difference between winning or losing the Competition. My clayshooting guns are in my cupboard now, with the safety buttons OFF. On some earlier model clayshooting guns the safety button could actually be 'locked' in the OFF position and some of the live pigeon guns that I have seen, did not even have a safety catch. So, the shooting routine should be, remove gun from slip BROKEN, enter firing point, load gun, call for and shoot target, open gun, repeat as required until finished. With open and cleared gun, leave stand, replace gun in slip BROKEN, close gun and fasten slip, then move to wherever. You will see that I did not even involve the safety catch. This method has served me well in over 55 years of both game and clay competition shooting without any ND's whatsoever. I have had 2 accidental discharges when shooting, but that had nothing to do with the safety catch. In my shooting career I have seen many accidents and 'near misses', none involving a safety catch and in my one incident of actually being shot, I was unable to reach the shooter in time to apply the safety catch on his gun before he fired !
