Basically brand new (see date on invoice in photo)
Have been on the fence about keeping my P9 for a while now (thinking I would rather have a full sized 9mm) and bought this drop in barrel from Kahr to see if it might be the sufficient compromise. Took it out today and put 40 rounds through it. It functioned perfectly, but decided to sell the P9.
Note: second photo shows what barrel looks like installed (gun not included)
