IIRC, CDNN started making you call for prices after a BIG credit dispute with Citigroup, where Citi froze $75,000 in card collections because CDNN was 'illegally selling guns via the internet, or something of that sort. I think they stopped publishing handgun prices online as a means to "improve" their image to the "politically correct" outside world.
Like it or not, they made that decision under pressure. I'm just glad they're still in business. I haven't heard if they ever got their money back from Citigroup, it's been quite a while, but there aren't a lot of firearms dealers that can take a $75,000 hit and keep going like it never happened.
One thing that I've found with most "Call for Price" companies, including CDNN, is that they often have prices that are much better than the other guys. On new guns, it's an easy way around manufacturers Minimum Advertised Price policies. It doesn't bother me that much, and they're more than willing to give you a price when you call them.
They do publish most of their prices in their print catalog. You could probably get one sent to you if you don't already have one.
