That's a really clear breakdown of the GHM9's classification – thanks for sharing! It's super interesting how much the legal status hinges on that stock/brace distinction. Given its modularity, I'm curious to hear from others: for those who own or have shot the GHM9, what's your preferred setup (pistol brace vs. SBR), and what are your thoughts on its performance in that configuration for dynamic shooting or home defense?

That's a really good point about the versatility that modularity brings to the GHM9. It's awesome how you can really tailor it to your needs! Personally, I've always leaned towards the pistol brace configuration for the GHM9, especially when thinking about dynamic shooting or even home defense. The compact size without the SBR paperwork is a huge plus for maneuverability, and with a solid brace, it's incredibly stable and accurate. I feel like it strikes a great balance between a full-size rifle and a traditional pistol. For those who have gone the SBR route, what made you decide to go through the NFA process? Are there significant performance advantages that you feel make it worth the extra steps, especially in terms of recoil management or accuracy at longer ranges?
