Item is exactly as described & what I expected, Arrived well packed & in perfect condition. The seller was in contact with me because of USPS sending the package the wrong direction, but still only arrived a day late. Not the vendors fault, at all. But appreciate their contact with me . Will be using again. A+ experience

Fast shipping, decent pricing and a real OEM Glock firing pin! You have to be careful because many sellers are selling “OEM Firing Pins” but when you read the descriptions it’ll say made per OEM specs. But this firing pin is a real OEM part. I recommend this seller.
