Genuine glock magazines with b&t spc9 - Glock G17/34 9mm Luger 33 Round Pistol Magazine

Have had issues in the past with 3rd party Glock double stack style magazines having feed failures and not holding the bolt open on last round with my SPC9. But official magazines work every time. Same polymer and steel reinforcement, and same bolt hold open make these reliable to the point that they are boring. Exactly what you want from a magazine. Now if only OR would stop trying to outlaw them.
