I am looking at a p89 pistol and most I see come with 10 round mags due to them being made during the ban. What are the things to look at when buying the 15 round replacement mags? Ones to not buy or stay away from ones that are good ect. Should I look at only Ruger OEM or after market is OK? Thanks. I see these guns are starting to go up in price. I used to see them all the time on GB ect for around 200 to 225 now they seem to go regularly for 325 to 350. Are people realizing that they are great guns or is it just that guns are selling due to the fear factory?
