UPDATE- Still have these and need cash to pay bills! Price Drop... $125 for both or $100 for the barrel and $40 for the spring system... I have up for sale two items from EFK Fire Dragon out of Arizona for the Glock 23 or 32. First is the barrel in .40 caliber- 4.02" length with a .16 left hand twist. I have only put 50 rounds down the tube and it is very nice but I am selling the gun it goes with seperately. $150 new Second is the EFK Dual Action Buffer Spring System for either the .40 caliber or 357 Sig. $65 new I would like to get $150 for both or I will sell the barrel for $115 and the spring for $45. FTF in either Clackamas or Newberg is prefered.
