How close does this triggerguard in specs come to D.D. Ross M1 unit for inletting on a stock? Also if stock has pillars already installed,would the pillars included with Lumley unit not be needed. Read somewhere that Lumley was inspired by the Ross triggerguard's shape and form. Sounds like a solid unit. Was wondering with all the different shooters on this site,maybe one had hands on experience with the Lumley unit. Like the steel construction of the triggerguard and the AI mags.would make reloading rifle easier/faster.
