Was there ever a determination on the difficulty adding a stock to these pistols once SBR'd or a barrel extension is added? I would seriously consider purchasing one of these, but only if I could add a stock at some point. I would probably just SBR it over pinning a barrel extension, but I would have to do something, as I think it loses functionality as a pistol.
What are the options when it comes time to add a stock? New trunnion - drill rivets out, re-rivet a new trunnion and weld up the old rivet holes? Is this the only option?
