Unfortunately in the shotgun world, a pump is seen as utilitarian and is only 2nd to a single shot. I watch these European show where they don't really bash pump actions but rather passively look down on them. The English are the worse. Just watch an episode of the Gun Room on pump action and you will see what I mean.
I personally think that the Europeans are envious that an American could invent something so profound that it help changed the course of history or at the very lease, a war. Ironically John Browning also invented the over under, a gun that the English covet but an over under never scared the Germans to the degree where they petitioned for it to banned for use in war.
From what I can tell, pump action shotguns are most popular in North America and as fairly young countries, both Canada and the United States need inexpensive tools for nation building. There isn't a lot of money around when one is first starting out. And at the turn of the 18 century, the concept of old money is really a European thing. So over time, we have gotten use to inexpensive pump action shotguns. I think that the BPS is a quality pump gun but is a bit of a pariah because the pump shotgun niche is dominated by inexpensive, rugged and reliable guns. The finish is a bit better than other pump actions but the question then becomes how much more money could that command and the free market, the answer is, not that much more. The only other thing that Browning has is name recognition but lets be honest, the BPS never had a military contract whereas the 870, 500, model 12 and 37 cut their teeth in some of the greatest battles in history. Don't get me wrong, I've wanted a BPS for awhile but I can't justify the price point when there are so many other inexpensive, well built, battle tested pumps out there. I am a huge fan of Brownings and own everything from 1911-22s to A5s to BPSs which I don't mind paying for but it just seems to me that the BPS for what it is, is about $250 over priced. That the cost of a Tokerav or SKS!
