There's no need for a safety catch if you are muzzle aware. In fact many fine guns were built without them. Such as the Winchester 1892 and 1894 rifles and 1897 and 1912 shotguns. The best safety catch isn't the one on located on your gun it's the one located between your ears. And if you are in a situation where you think you need to have it applied "in case the gun fires accidentally" then you are actually in a situation where the gun shouldn't have a cartridge in the chamber(s).
I’ll be rethinking how I carry my rifle now (in terms of round in chamber etc).
Just thought I should post honestly so that it reminds people to be careful!
