Glock 19 Magazine Base Plates & Extensions

Replacement Floor Plates, Finger Extensions, and Capacity Extensions

Browse magazine base plates and extensions for Glock 19 magazines at NDZ Performance. Compare standard replacement floor plates, extra-thick profiles, finger extensions, and capacity-increasing options. This category brings together G19-compatible products across the generations supported by each listing.

Choose by function first. Standard replacement plates offer a different finish or appearance without adding rounds. Extra-thick plates and finger extensions provide additional surface area, but an extended profile does not automatically increase capacity. Capacity extensions are identified by the capacity change stated in their individual listings.

Confirm the supported generation, magazine manufacturer, caliber, original capacity, and any magwell requirements before ordering. A plate listed for one magazine configuration should not be assumed to fit another. Review the product description for exclusions and any required components.

Compare the available materials, colors, textures, and finishes after confirming fitment. Products marked (*LZ) offer laser engraving options; available designs and personalization choices vary by listing.
