The friend I convinced to join the FN family by purchasing an FNX-45 then FNAR -still on him to join the Forum he may have a DIY remedy for the rail issue with the FNAR, his HAD it too- is having issues with the mags and slide release. They are as follows, shortly after first shoot with the .45 he found one mag to release the slide when reloading, I checked the mag out and compared it to the remaining 2 but didn't see anything unusual. In subsequent shootings it would do the same thing but not always, he identified the demon-seed mag and continued shooting using the other two without issue. Today while zeroing the scope on his FNAR we spent some time shooting our FNX's and another demon-seed magazine reared its ugly head and is now doing the same thing. Any known issue or reason this might be occurring and or any way to check? Thanks...
