SPF....got my wife this vest pistol for jogging a few months back and have had a blast shooting it myself but finally got her to the range this last weekend and she's having a hard time getting the slide back. So I'm looking to trade it for a snub nosed revolver with cash on my end. I've put 75 to 100 rounds through this and have not had one issue. Ill throw in 25 rounds of fmj and 5 rounds of hp. Made around 1968. Pm me with questions thanks
