There are two things of which to be mindful here.

Matador is the name AyA gave to that particular shotgun.

Pride of Spain is a name created by a US retailer for guns he bought in Spain, from whichever maker would meet his price point for each batch of guns.

The significance of these two things is this:

The name Matador tells us who made the gun and the price point to which it was made. The name Pride of Spain does neither.

Folks who make much of the acronym POS may want to consider why the Chevy Nova was such a flop in Spain.
