My 2400KT (top) has a new best friend (bottom). It was a 1322, but its all custom, & closer to a 2289 now. A couple more parts are on order to complete the project, but this is more or less it's final layout. The peep sight is a fiber optic ghost ring type. It works great (for the length of my basement at least), and helps to keep it all compact and light weight. The fiber optics may turn out to be too bright in daylight for precision shooting, but for now I'm really liking them. The stock pops off with a button, and I can holster the resultant pistol. http://micro.fragdev.com/attachment/62715
