ATF Details on Shoulder Stocks
At the urging of GT Reader Kelleher, we get way into the weeds of NFA, SBR, and C&R regulations. Also, Reader Landers details whats hes done so far to get his Diamondback pistol to work.
I have recently acquired a 1911 pistol with shoulder stock and correct mainspring housing, so I found your test on shoulder-stocked pistols to be quite timely. My understanding is that attaching a shoulder stock to a handgun changes a legal firearm into an illegal short barrel rifle. A police officer/friend I talked to agreed. I ordered a 16-inch barrel, so I should be legal. My stock has no markings on it, and the only info that I can find stated that it was made in the 1970s for covert operations. There may be some nuances in the law that I am not aware of. Perhaps Gun Tests could clarify this for future buyers/owners of such accessories.
