I suspect everyone here has a gun or two in their collection they just wish they'd have waited until the first round or two of issue of their 'prototype' they decided to sell was over and they had worked out all the kinks and problems. I have two. A pistol that shoots 22 WMR and has a big magazine capacity and the other is a novel short 12 gauge shotgun that also has a large capacity. Many problems with the pistol and the shotgun is just too finicky...
