I'd say you did pretty good on the deal. That's less than what a new FN Hi Power is selling for currently.
Factory 13-round magazines are fairly expensive, generally running $50 to $60. If you keep your eyes open on the auctions and other web-based sellers, you can sometimes get some fair deals.
Right now the South African 15-round and 17-round magazines seem to be the way to go.
CDNN sells them NIW for about $20 each.
A second option is from a guy who advertises on Gunbroker and Auction Arms under the name of "reddoggxx." His name is Paul Hadella and he sells what he calls "Canadian Military" 13-round magazines. Some sources say this is not so, but Paul is pretty well-known over on czforum.com and stands by what he sells (he'll refund your money if they don't work). I've bought CZ magazines from him and he's been great to deal with and says these Hi Power magazines function great in his mid-seventies HP. I'll be including some HP magazines with my next order. At any rate, he'll sell the magazines two for $30 shipped (cheaper than his auction prices since he's not tagged for any fees) and is set up to take Paypal. You can contact him at
