Yeah, I'll call bull#### on that, for a couple reasons.
They are not going to spend more time in the fit/finish department on a hunting rifle, fit a full length hunting stock, heavier firing pin spring/extractor, larger chamber, just to have a gun that you can shoot 40 year old corrorive surplus FMJ that you can't hunt with anyway, and shoots like ####.....all for a 50% premium.
My CanAm $375 special shoots surplus just fine, the firing pin spring was so stiff I cut a couple coils off it to make cocking and trigger pull a bit lighter, and it still fires surplus fine. The firing pins are adjustable for protrusion, and I suspect the ones that don't go bang with surplus just need another 1/2 turn to work reliably.
Also CanAm brought in thousands of these(?), and Corwin brought in what, a few dozen?
Zastava could care less about the Canadian market. At best, even with the CanAm bulk purchase, we're a rounding error in their overall sales.
They make different levels of rifles, fit an finish wise, primarily for the European and US markets. Saying that all their M85's are the same is like saying that an 870 express is built to the same standards as a Wingmaster.
The firing pin and extractor upgrades are readily available as options from the factory, and are available as aftermarket parts upgrades. Poke around through this forum, and the ones in the US, and the firing pin and extractor issues/upgrades are well known. Actually, there's some great info on the Zastavas on some of the New Zealand gun boards - they're very popular over there.
The Stutzens were brought in by Corwin-Arms and TradeEx (TradeEx still gets them from time to time). CanAm did a bulk purchase of the most economically priced model they could - which is fair enough, they aren't bad rifles.
The downside is that CanAm did their bulk buy, then for some reason the relationship went sour. CanAm posted in their own forums that they would no longer be importing the Zastava's "for business reasons" (their words, not mine). AFAIK, TradeEx is the only one still bringing them in, and not in large numbers. The CanAm buy set a price expectation for the rifles that wasn't sustainable, so now the imports are down to a trickle, because no-one wants to pay $600-$700 for them, which is what they need to retail at under the current import conditions in order for anyone to make a profit.
It'll turn around eventually, and we'll see more of them available. They're a good, solid, "working man's" hunting rifle. Are they comparable to the CZ's? No. But even in the $600-$700 range, they present a decent value for quality proposition, especially when the CZ-527 runs for about $1,000 nowadays.
