whats the best way to attach a sling to a 940 or 630.Both of mine have the slotted head "screw" that fills the hole in the stock.These "screws" are like coarse thread metal plugs approx. just under 1/2" in dia.
Those slots are for Pachmayr q.d. sling swivels. If you can locate a couple sets, they are a pretty slick way to mount a sling.
