I can understand being a little nervous about ship someone else's gun that you don't know but they are the one who is trusting you with it and should be aware of all risks involved. And to go along the lines of the CZ I was in Highsmith Guns in Greenfield a few days ago and there was one with a decocker can't remember the exact model. It seemed nice but I don't really know much about them.
Do you happen to recall what their rental charge is? I looked at their website, but it only mentions range fees.
