Yes, the problem is ejecting a long relatively small diameter rimmed cartridge w/o a place for traditional extractors to operate. That’s why blowback .22 Rimfire semi-autos are such a pain in the a$$. I have a Sig .22 LR semi, and it almost doesn’t work unless I use CCI mini-mags. It is the most unreliable pistol I have. I bought it as an “emulator” for my centerfire Sigs, but it’s not something I’d ever have to protect myself with.
