What kind of damage are we talking about? This is the way I have let the hammer down many a time after cleaning ect. I thought this rule only applied to rimfires.I have one and really like it, but I don't have a good holster. Mine gets carried in a universal type belt slide when I carry it. One caution, don't dry fire it with the magazine removed as it will cause damage to the gun. There is a lot of talk about this over on the ruger forum. Might want to check there.
