Sky is the limit
Picatinny allows just about anything to be added to your pistol. You want to mount an LPVO to become a sniper? Go for it. Nothing is stopping you! Although, the eye-relief will probably be too short for it to be useful.
A Picatinny rail designed specifically for the SSP5. Attach any optic you want to your pistol and make it truly unique.
Choose the length based on which SSP5 version you have.
The long toprail is compatible with the SSP5 6″ and the short toprail is compatible with the SSP5 5.1″ and the SSP5 4.3″.
