All of the optional accessories that are available for the standard P500 Universal Sight Tool are in this P500 PRO Universal Sight Tool.
Added a two position Hold Down Clampo that is attached to the tool. This speeds the set up time, and greatly increases the strength of the tool, by preventing the slide from lifting or twisting.
Also added an End Plate to add strength and it doubles as a Slide Stop.
The most important additions are the newly designed Pusher Tips. These hardened steel tips use the cross member as a guide to prevent rotation that may cause scaring of the sight. One of the tips is squared on the end for standard sights. The other is made with an angle to fit against a tapered sight, such as the Glock.
