As I've said 100 times before ... the only gun to lose value quicker and have less interest generated in the used market than Ruger CF semiautos, are Tauruses. The Ruger revolvers always do very well.
In my area, used P-series guns go for $175-225 tops ... MAYBE $250 if it's stainless and has ALL of the paperwork, box, shipper, etc. The P90 is a little higher.
Most dealers in my area won't even take a Ruger CF semi in trade at all, but that generally doesn't come into play because when a seller hears the number that's offered, they generally storm off in anger.
The bottom line is ... whether Ruger semiauto afficionados like it or not, there is VERY LITTLE demand for the CF semis from Ruger outside of people who are ONLY looking for Rugers. The primary reason is the lack of accceptable accuracy compared to other comparable guns in the marketplace. Virtually ANY Glock retains about 80% of it's value FOREVER. A little less percentage wise with the CZ line, XD line, and even the S&W M&P's.
The plastic Ruger semis are particularly bad for value retention, and of course the recall affected guns as well. There are dealers in my area that have had the same new P345's in their case for years, and they don't sell at ANY price.
If you buy a new Ruger CF semi, you better plan on keeping it, unless you're willing to lose about half your investment immediately, or sell it here to someone who doesn't know about them yet.
Before everybody jumps all over me saying that THEY'VE made money selling used Ruger semi's, we're talking about the used semi market as a whole, not the small niche that exists here on the forum. And I know, most guys here will say that THEIR Ruger semi is 'super accurate', and they shoot it better than Glocks, Sigs, Colts, etc, etc. If that were truly the case, the shooting world would be well aware of it. It doesn't take long for the shooting world to find highly accurate guns and buy them ... repeatedly.
