If Ace lock didn't think the inside tang wasn't necessary for proper safe continuous operation of their tubular lock they wouldn't have wasted time building it into their design.
Sure many other manufactures decided to not incorporate it for one reason or another but they may have not understood the main reason it is there "to drive the lock not using the pins that can bend and be marred from sideways pressure. This is why I said not good to use a no tang super thin walled bullet shell for a lock meant to have a tang to drive the lock as with a heavy monetary switch lock with return spring or a tailpiece that binds because it is too tight as with many that have been installed and not adjusted to relieve that pressure.
Yes some cheap tubular picks may not have a tang but are also not designed to be used as a daily key on the same lock either. Picks with no inside tang is a horrible design as using it causes the pins to bind in the upper section and not just at the shear line which makes it harder to pick.
My point in saying using the 38 shell is good for show and tell but not for a lock in use by a consumer is it is thin walled and if not perfectly center of the round pins sides it will eventually start to bend either to the inside or outside area of the pins because it is using the pins to drive the lock.
Even if that doesn't happen it has the potential of knife edging into the sides of the pins making a raised burr on them. If for some reason the lock slipped passed and relocking in wrong position and then the key is inserted in wrong position some pins will be pressed way below below where they have been operating and jamb up staying in the down position because of the pins being slightly bent or have marred sides. This can happen with pins being pressed down passed where they have been working just because of dirt and oxidation build up. Plus using just the pins to turn the lock will eventually egg shape the holes. A little thinking about this should become clear it is a bad idea. Just because some lock manufactures decided to ride the coat tails of the ace lock design and change it a little to be different enough to not infringe on the superior ace patent doesn't make it proper. Doesn't take but a very little side burring of a pin to have it stay stuck in down position.
Love the look of the 38 shell as a key but if put on the market for public use especially on a vehicle such as a Harley it best have a drive and index tang or they are begging for problems.
