I picked up a Model 320 security a year or two ago with the ghost ring sights and the pistol grip stock, which seemed kind of uncomfortable for some reason. I took it to the range for a function/accuracy test and it worked flawlessly, except for the pistol grip stock which made reaching the slide release a little awkward. I looked around for a regular stock, no joy at all, then a family member gave me an old poorly repaired wood stock he had gathering dust, I believe it was from a remington 870, it only took a bit of trimming to get it to fit , the crack was easy to repair and I used some epoxy putty to modify the grip, sanded and sprayed it Matt Black. Turned out better than expected.
