Hey folks Yesterday I went to the local pawn shop and bought a Mossberg Model 75 bolt action single shot 20 guage for $85. The barrel has already been cut down to 19 inches. I bought it just to have something light weight and fun to shoot. I was planning on having a little fun with the gun and maybe doing a little engraving on the receiver and stock but also cutting the stock down and making it into a pistol grip. I was wondering if it is legal to make it a pistol grip? I know that the barrel has to 18 inches and the full gun 26 inches. I've done some research on the internet and it's got me confused. I was also wondering about the laws on PGO shotguns. What has changed? Was curious because I own a Mossberg 500 Cruiser. By the way I live in Oklahoma.
