"The Universal" 140mm Dry Weight Magazine Insert

The Universal 140mm Dry Weight Magazine Insert (9mm Double Stack)

The Universal 140mm Dry Weight Magazine Insert is a highly versatile dry fire training tool available at JV Training Accessories that is designed to fit a wide range of full-size 9mm double-stack magazines. Built for competitive shooters and serious trainers, this insert replicates the weight and handling of a fully loaded magazine while eliminating the need for live or dummy ammunition.

Product Overview: Universal Dry Weight Magazine Insert

From JV Training Accessories, the Dry Weight Insert replaces the internal spring and follower of your magazine with a precision-weighted core designed to replicate the feel of a fully loaded competition magazine.

This creates a consistent, realistic training experience for reloads, transitions, and dry fire practice.

Key Features & Benefits
