This is a used Glock OEM Gen 1 and/or Gen 2 "pre upgrade" Black locking block #308, made for older 2 pin models G17 & 17L pistols. It will also fit a G34 2 pin, but the G34's were never made with black parts because Glock did not start making the G34 until 1998. Upon inspecting this locking block, It appears to be in real good shape. It does have signs of wear, where some of the black coating was rubbed off. But it does not look like any metal was worn down.
I do not have any factory packaging or papers for this item. It will come shipped in a zip lock style plastic bag.
Please see the high resolution photos for condition.
I will combine shipping on multiple purchases.
Thank you for looking.
