14mm CCW Thread adapter. With the typical threading, you can mount all kinds of tracer units and suppressors to your SSP1.
We recommend the short tracer unit. Since the SSP-1 has a dropping barrel, suppressors and heavy tracer units will stop the pistol from working properly.
It will not fit for the SSP-1 of Americans and Italians – since those have an orange tip glued into the outer barrel. Outer barrel without an orange tip is available in the spare parts.
