Well, yes, in the big picture. The real crux of the issue is flush mounted magazine vs one that protrudes below the bottom of the gun. Happens that Ruger's plastic (and steel) magazine is flush mounted, few others are. The reason it matters is that the magazine is at the balance point on the gun so if you're carrying it one handed, you've either got a smooth Ruger surface to hold onto or you've got sheet metal gouging you in the hand.
If you've got some other magazine that flush mounts with no protrusion, good. If you've got one with a smooth floor plate ala 700 or 70, good. If not, bad.
Simple. And it doesn't require being an asshat playing childish "got it" games to "understand."
