Since the OP said he wanted a manual safety, it seems that the Rohrbaugh R9 and all Kahrs are out of consideration.
You're right. He asks about whether he should get a safety or not in his first couple of posts but decides at post 21 he wants a safety. Oh well, that narrows the field down quite a bit.
Jim's Rules of Carry: 1. Any gun is better than no gun. 2. A gun that is reliable is better than a gun that is not. 3. A hole in the right place is better than a hole in the wrong place. 4. A bigger hole is a better hole.
no guns = might makes right
