Good morning, I found a used Walther CP5, but it hasn't been fired for 10 years, so do you think I need to do the maintenance? If so where is what value could it have now.
To be clear, it is the one that shoots 5 shots in succession, electronic trigger
Usually the battery needs replacing at some point, but if it works it works. I would personally drop some silicone oil in the ports to oil up the o-rings internally for longer life. Also these are not very hard to replace the O-rings on, so no worries there really. It can be worth quite a bit, up to 1k if in very good condition. They sure are a lot of fun to shoot. Though most people are a bit leery because of the electronics, shooting folk usually have more faith in mechanical things =-)
