3/12/2026 UPDATE:
At this time, the tungsten market is experiencing significant volatility. The material is heavily manipulated worldwide, particularly by Chinese suppliers, and many companies have been caught in scams or unstable deals. This has driven U.S. tungsten prices sharply higher, making it challenging to source material at a reasonable and trustworthy rate domestically.
We do have the Gen6 design ready, but we cannot provide a clear release date until the tungsten market stabilizes and we secure a reliable U.S.-based supplier. We are actively working to find a fair and dependable domestic source.
SSI TUNGSTEN SLUG Grip Weight for GLOCK
- Perfectly legal to race in USPSA
- IDPA confirmation pending... UPDATE:Section 8.1.7 of the current rule book states covers Non-IDPA Legal Features and Modifications for All Division. Under that section, rule 8.1.7.2 states, "Add-on weights that have no legal operational function other than providing weight". So it therefore does not appear to be allowed under the current rules.

This grip weight is fully CNC machined out of Tungsten. The preinstalled Nylon GRIP PLUG keeps it all togeather and cleans up the reload path into the magwell. This weight is the heaviest ever made and will put the weight where it needs to be, in the grip of your hand. If you are looking to get that competitive edge to better control recoil and have a functional GRIP PLUG then here is your solution. Dot shooters reports: the dot stays in the window.
CUSTOMERS WITH MAGWELLS: We stopped the tungsten at the fastener hole and the feedback we have from customers is... I shot it without my magwell and it felt so good!!! I didn't want to reduce weight so I just flat sanded the magwell mounting plug to just touch the SSI Tungsten slug. So MANY customers are modifying the magwell mounting plug to work and are very happy.
USPSA Maximum allowable weight Production Division is 59 oz with mag inserted

... As we have worked through suppliers of material and local CNC shops, The slug that you get may look different than pictured and could weigh more than advertised. Fit and function is not a problem.
