Jeffman is 100 percent correct. Your SL8 will accept either double or single stack mags. The single stack have a little play in them but they feed well and hold the bolt open on the last round.
Update I posted this in another thread regarding the use of single stack SL8-6 mags in a SL8-4 or 5. Hope this assists.
