I'm not aware of any fixed 4x handgun scopes these days, other than the used market. What handgun are you planning on putting it on? Could you get by with a fixed 2x scope? I put a Burris 2x handgun scope on my Ruger Redhawk 44 Magnum last year and so far, it's holding up well. The Ruger previously had a 2x Leupold that got damaged beyond repair and sadly, the folks at Leupold don't seem interested in making handgun scopes anymore. 2x is quite adequate for handgun cartridges like the 44 Magnum.
