thoughts on pcp shot guns?

I have PERSONAL EXPERIENCE of a Korean pcp shotgun Fire 201 some years ago. Absolutely rubbish for its intended use unless you intend to limit your shooting to under 10 yards or so. It shot so-so with cast pistol bullets a lot better than it's intended purpose. That's it...oh excellent noise maker! Kinda sounded like a real shotgun when shot! YO!
