I wish he had kept the original stocks in the box. I'd love to know what they were and looked like after his service. I have no idea when he put the targets on but, they have many years of wear on them, too.
Just speculation and I not knowing his shooting habits, I think he likely used the magnas before retirement. Afterwards He bought the target stocks. Those kind of targets without the relief cut are kind of hard to keep from getting banged up from ejecting casings. I would be curious if the gun fits the holster well with the target grips. I think the holster being so old that it might be shaped for the magnas even now.
Since I cannot see the name does it appear to you the name was added before or after his service?
I would also be curious if the gun lettered to a hardware store where he bought it or if it was part of a police shipment.
