Up for sale is a lightly used Bar-Sto semi-fit barrel for Gen3/4 Glock 34 9mm pistols. Has about 300rds through it. Only selling because I sold the pistol that it was in. I have another one in a different 34 and it's a laser. This barrel was carefully fit to my Gen4 to ensure snug lock-up while still being 100% reliable. It should drop-in to most pistols, but it may require a tiny bit of fitting. These are $250 plus shipping new, asking $130 shipped. Prefer Paypal F&F or Zelle. Thanks
