Now you can take that Ruger pistol and drop it in a rifle stock and it's still classified as a pistol and legal to use.
In T/C it is the receiver that is classed as rifle or pistol, so you can put a 21" rifle barrel and stock on the pistol and it's still a pistol and legal. Now if it's a "rifle" receiver then you can't put the pistol barrel on it and be legal, even though they are basically the same.
The thing is with a T/C you can probably get away with the switches (the install of pistol barrel on rifle) because of mfg offerings of receivers that are almost identical for pistol and rifle and who would know until caught doing something else that was illegal. To me being a 10mm shooter and having a G2 Contender pistol and a 10" barrel in 10mm auto, the thought of buying a rifle stock is intriguing to me, but I just don't see the need for spending the money.
The T/C for me is just a range toy, not a hunting or defense gun. I have G20/29 for personal defense and several large bore rifles for hunting or target, the G2 was more of an idea for 10mm test bed gun that has sprung out of a failed idea of using G2 as a first gun for a young grandson but the 12" bull barrel was too heavy and trigger reach too long for him.
This is not correct. Check with BATFE. There are numerous kits that involve adding a stock to a Glock and these all require that the pistol be registered as a short barreled rifle. Same thing when putting a folding stock on a Heckler & Koch SP89 pistol. Also, you cannot buy a AR15 pistol and then simply put a stock on it. The fact that it is built as a "handgun" is irrelevant. If you take any sub-16" barreled firearm and turn it into a shoulder fired weapon without registering it as a NFA item you are committing a federal crime.
