I also love the SCD, and never owned a Glock prior to being able to have one. All of my Glocks save the G44 have one, and the G44 only doesn’t have one because Tom never sold one for it. I think (hope) I still have a spare in my parts bin.
I sincerely hope someone takes up the SCD either as a primary product or as an accessory, but either way, maintains the quality and QA/QC Tom brought.
