I spend some time watching youtube and get some interested thoughts based off of what I see. I don't expect that I am the first person to think of this, but is .380 ACP with moon clips compatible from a .38 special? The number is .002" off I think. The thought came to me while watching someone shoot .32 ACP out of a .327 Federal Magnum handgun. That handgun shoots the .32 S&W, .32 S&W Long, .32 H&R Mag, .327 Fed Mag, and I saw him shoot .32 ACP. It seems like being able to shoot a .380 ACP out of a .38 special or .357 mag would be beneficial in training novice/sensitive shooters. I know there are other options for this, however this has me kinda interested.
