This terminology is grinding on my nerves!! None of the classic North American double gun manufacturers ever advertised a Prince of Wales (PoW) grip!!! Straight grip, half-pistol grip, quite a few Parker Bros. hammer guns with a ball grip, and a full pistol grip. What the North American manufacturers called a half-pistol grip is not at all like what some of my English gun catalogues show as a Prince of Wales grip.
I'll take that under advisement. When I piss someone off, I like to have intended to.
