An addendum to Fingers...(I am all thumbs)
In my opinion you are well advised to be thinking about removing the nipples to clean the pistol each time you shoot it.
Many say it is not needed and likely I am being too fastidious. Indeed some never remove the nipples unless they need replacing. But I like taking the nipples out every time. A by-product of this is that nipples don't get tight and almost any nipple wrench will do and more importantly will last a long time.
My reading of history convinces me that most bad government results from too much government. Thomas Jefferson
