Don't know for sure, but CDNN may have bought the last of the ones that were being offered earlier this year by GSI as "demo", "refurbs" etc. to dealers at the price they are offering. The kicker is the 1 mag. NIB Steyr M/S series come STANDARD with 2 mags. So their price is not great, if you count the 2nd mag, it comes to $395, which is about what they were wholesaleing for before the wholesalers ran out. And those were NIB, not "refurbs", or reworks. Now I like CDNN, I've bought from them before, but I don't like the tactic of charging extra for the mags that are supposed to come with it.
Granted, now that imports have been SUSPENDED temporarily, if you want one NOW, then that's a good price. But I fully believe that GSI will be importing them before the end of the year.
FWIW, I paid $415 for my M357 DELIVERED, and $425 for my S9 DELIVERED. Excellent prices for good pistols.
To buy from CDNN, I would have to pay TX sales tax
Unfortunately, GSI is not too prompt in responding to emails. I sent them a note about a .40 S&W barrel, and mags to add to my M357 and they never responded. May have to call them on Monday.
M357 shoots great. Haven't shot the S9 yet.
