Here are some examples that I found to be WAAAAY out of line for a gun show.
XD-40 sub compact $550
XD-9 service $550
XDM-9 service $650
Mosin Nagant $179
Taurus PT111 $389
Kel-Tec P11 $325
Kel-Tec P32 $299
Rossi .357 $389
S&W Sigma $369
Used guns were just as bad
1st gen Kel-Tec p32 $279
1st gen Glock 23 $450
Maybe they are out of line for your region, but most of those prices aren't too bad for my area. Not good, but not total rips either. Only the NIB Rossi .357, S&W Sigma and used Mosin strike me as being out of line (again, compared to the prices I've seen around here).
Here are some of the gems I've seen in NC lately. I wonder what grade of crack these idiots must be smoking when I see stuff like this:
Used S&W 686-3 6": $750
Used Ruger GP100 4" blued: $650
Used S&W Model 10-9 4": $500
Used S&W Model 681-3 4": $500
Used Colt Detective Specials: $700-800
NIB S&W 642-2 (no CT laser grips): $479
NIB Heritage Rough Rider Combo, blued (22LR): $250
NIB Spinger XD9: $600
NIB Century C15: $1,000
NIB CZ75B 9mm: $600
NIB Charter Arms 38 Snub: $389
SKS prices have spiked the most, percentage wise, from what I've observed. At the Raleigh gun show today, the
cheapest SKS I could find was $250. It it was rough. The average price was about $450.
I saw two
Russian SKSs (in very nice condition) for, drum roll: $
1,000. EACH. I was stunned. Maybe they were autographed by Nikita Khrushchev or something.
I also recently saw a Mosin Nagant M91/30 dating to 1942 (Izvek? I believe) priced at $750
Geez.
Of course, there were some deals out there. I got a load of small pistol primers for significantly less than my local gun shop. I also picked up some lead .357 bullets from GA Arms (500 for $30). I saw a very nice Colt Gold Cup 1911 for $700, a S&W Model 19 4" for $350 (it did have some end shake though) and a NIB 38 Special Ruger GP100 for $399. I also saw a VERY nice 27-2 for about $600 - not a steal, but not bad either.
So there are some finds at gun shows, but they seem to be the proverbial "diamond in the rough".
