A device implementable on a firearm includes a magazine funnel and a securing mechanism. The magazine funnel is configured to couple to an opening at a bottom of a grip of the firearm. The magazine funnel has a first side and a second side opposite the first side. The securing mechanism protrudes from the first side of the magazine funnel such that, when a gap related to the securing mechanism is expanded while the magazine funnel is coupled to the opening with the securing mechanism inserted into a void of the grip, the securing mechanism secures the magazine funnel to the grip of the firearm.
