HKParts.net is selling this Dakota Tactical made padle mag release pin and bushing (pictured). It uses a 1/8" diameter axle pin. Since the diameter is 1/8" is it legal to drill both sides of the receiver and weld in place? (I know the standard/factory diameter pin can only be drilled from one side). If it's a drill through legal set up I'm suprised it's not listed as such in the item description as it's a huge selling point for all the non padle mag equipped C93's floating around. Just curious and couldn't find it in the add or search and the pin is longer than the magwell area is wide.
