A lot depends on how many times its been pawned. If they've made money off the gun several times already...they may cut you a heck of a deal. Never hurts to ask. I go in knowing I don't have to have it. I picked up a like new s&w 36 snub for 200otd the other day...but this same place will ask 149 for a used marlin 22 you can get from academy for 129...and they'll let it sit for 2 years.
