Recently purchased a very slightly used 27. The prior owner had installed a belt clip which I'm not at all fond of especially with a gun that has a trigger safety. While I immediately removed same and gun was function without it, it included a receiver back plate with 2 screws that for various reasons I didn't like. Went to a gun show this morning and took the Glock to their stand and asked for the stock part. Part was retrieved and installed for no charge. Just another perk for owning a Glock which I appreciate. Just sayin'
