I purchased a Glock 30sf from JB-Glock21 last week. He had kept the gun in mint condition, still in the original case with extra magazines and a loader. He was nice and friendly, easy to work with. This weekend, I took the gun to the range to test alongside my Glock 21 and my wife's 302. This gun held it's on. No defects or problems whatsoever. Thanks, JB!
