I am looking for a Scherer SP5 plug for a glock 21sf. I am unable to locate one at my lgs and cheaper than dirt is out of stock. If anyone has one or the ability to get one from their lgs please advise a purchase price plus shipping to zip 32927. I am not interested in the jentra plug as I prefer the protrusion of the scherer that acts as a guide ramp for the mag into the mag well. Thank-you for any help.
