Oh, blah blah blah. The grips in question cost a lot, because of MARKETING strategy and product alignment. This simply means, in this context, that they are made for a relatively expensive pistol......so Hogue can probably get more for them..... so that is what they charge. If they could get $1,000,000 per set for them, then that is what they would charge.
Like most simple manufactured products these days, they probably cost less than $10.00 to make. Interestingly, gross profit margins on the SIMPLE items, such as these grips, as a percentage of the manufacturing cost, usually far exceed the margins on complex products, such as the gun they were designed to fit.
But, in any case, it comes down to marketing.
