Works great - when used with the correct grip. - ERGO TDX-0 Tactical Deluxe Grip Plug

This works great, when paired with the TDX-0 (either flat top or with beavertail) grip. However, it is a different, larger shape/angle than the plug for the typical, angled Deluxe Ergo grips....which is likely what the previous reviewers were tying to use it on. Use it on the right zero angle (tdx-0) Ergo grip and it fits and works well!
