I have a quick question on the P-3AT's I am looking at ordering one online because none of the local gunshops here in Tulsa carry the Hard Chome models. My question is I have seen some Hard Chrome models with the grey frame and others with the black frame. Is there any difference. Also should I get a second generation or 1st generation model. I have read the posts on here for both but am still confused. How do I know which one I am getting online, do I just need to ask the seller if it is 1st generation or second. Any and all help would be appreciated. Thanks!
