Finally got the wife out to the trap line, and much to my surprise, she quickly passed up her old bantam 500C for my new full-size 500C. Watching her shoot the youth SA-20, I should probably put a normal length stock on it too. So, I’d be happy to trade either a PA-459 pistol grip stock which I’ve already confirmed fits perfectly on a Mossy SA-20 or an SA-20 youth stock for standard length black plastic SA-20 stock. Figured I’d try here before kicking myself in the nuts hard enough to make buying direct from Mossberg less painful. Holler if you’re interested.
