Huh, hadn't even thought of that--it could very well be the case. 1.000" for .22LR vs. 0.984" for .380.
OAL on 9x19 is 1.169"... by the time you account for the overlapping rims of the .22LR, I'd expect the magazine would need to be closer to the P938's size (front to back) than that of the P238. My guess is you just aren't going to be able to make .22LR work through a gun sized for .380.
