Wow... talk about DEEP DEEP DEEP concealment... would be great for some very last resort instances... but I don't know how great of an EDC it would be as a single shot .22lr.
I would just as soon go with a North American Arms 5 shot NAA-22LR-HG with "holster handle". Cheaper, roughly the same dimensions (if not smaller)... and 5 shots.
Oh its totally not practical for jack. It would be cool to keep in a bag as a last resort BUG. I like the creativity of it. Its still weird and kinda corny/gimmicky, but hey why not? These are the kind of things you buy now when they first come out. For example look at the Braverman non NFA Pen guns....they were like $100.00 originally. Now theyre like 1000.00 to 1500.00 on GB. Also look at the COP 357...I sold a used one on GB for 1300.00 lest than a a year ago.
