My 7600 pump, I used the thumb and finger trick to quiet it down, one finger and loud click. I also know guys who rather leave the action open and then close it upon raising the firearm (like nomercy mentioned). This is how I do it when decoy hunting waterfowl with the shotgun, but I have the saftey on as well. Never can be to sure especially when your laying down on the ground blowing on the calls and your buddies are not to far in either direction...safety is always number one with me!
I now only use bolts with top mounted safety, easier & more natural to slip the safety off in the shooting position, less likely to bump it off(IMO more safe) and three sound can be control very easily.
Simple resolve to this problem & you now have an excuse to buy a new gun/toy

. If married or have a sign. other that hassles you about spending cash on hunting, etc. " But honey don' t you want me to be safe!!!!!" works everytime. I have used it on more than one occasion (of course their must be merit), but after pulling the old safety issue line

...she always agrees
