So far I've stayed out of the NFA world, but with the brace rules likely changing soon, I find myself reconsidering. I currently have a couple of 11.5" braced pistols- one is a retro 933 clone I have for sentimental reasons (first issued rifle was a 933), the other is modern with a red dot/free float mlok rail/A5 buffer, which is my bedside/home defense...thing. With the impending brace rule changes, the 933 will probably get SBR'd as changing the barrel would ruin the sentimental aspect, but for the modern style one I've hit the analysis paralysis stage.
1) Assuming I'm already entering the NFA world for the 933, should I SBR the second lower or re-barrel for a P&W 13.x"?
2) If doing pinned 13.x", should I try to future proof the muzzle device, and if so, which attachment format (Keymo, ASR, OSS, etc..)? It seems like the SOLGW nox flash hider is the "easy button" for P&W 13.x" builds.
2A)How valuable is low back-pressure/blow-through for cans? I'm at the "I don't know what I don't know" stage when it comes to cans, but my initial instinct is that a low back-pressure/blow though design would make things easier in terms of hosts. I'm not one that really cares about having the lowest possible db, but taking the edge off the blast from shorter barrels would be nice.
