Yea, i hear you on size but it almost doubles 9mm capacity. It is only a matter of time before you see ccw 5.7 and bolt guns in 5.7.
I'm not saying it will be 22 cheap, but as demand grows and the big companies keep making it in America it will continue to improve and more available in bulk pricing
If prices get down to 22 mag levels, that would make it a viable plinker - for me.
I thought about one for my wife, but grip is too large for her.
