The Sure Plug is an essential accessory for use with the Glock ® pistol. It is an inexpensive part that serves several important purposes on the firearm.

As a aide in guiding a magazine into the magazine well, it will decrease the time required for those crucial magazine changes. It will provide the user with the assurance that the magazine will not hang-up on the bottom rear of the magazine well by providing a smooth, rounded surface to guide magazines into place.
The Flush fit of the plug also eliminates the possibility of snagging on the open cavity.
The cavity on the backside of the handle (pistol grip), just behind the magazine well, is hollow and open at both the top and bottom. This opening can allow debris such as Dust, Dirt, Sand, Snow, Lint and Water to reach the trigger assembly and firing pin of the glock hand gun. The addition of this simple and inexpensive hand gun part can eliminate the potential problems created by this debris. This alone is probably the biggest reason to purchase this accessory.
You do not need to be a Glock® Certified Armorer to install this part. It simply snaps into place and it stays securely in position. This is the most economically beneficial firearm part available.
