The Sig Sauer 9mm Luger suppressor piston with M13.5x1 left-hand thread is a straightforward way to reconfigure your existing Sig suppressor for a different host or caliber. If you've got an SRD45 sitting in your safe and want to run it on a 9mm host, or you need to match a barrel's thread pattern on another firearm, swapping out the piston is faster and cheaper than buying a whole new can. This piston is precision-engineered and finished in matte glass bead, giving it a durable, low-glare appearance that fits the aesthetic of serious suppressors.
Sig Sauer manufactures this piston from 17-4 heat-treated stainless steel—a material chosen for strength and corrosion resistance under the thermal and pressure cycles of suppressed fire. The matte glass bead finish protects against shine while resisting wear and fouling. The left-hand M13.5x1 thread pitch is a less common configuration, so verify your barrel's thread spec before ordering to ensure a proper fit.
Installation is straightforward: remove the original piston from your suppressor body and replace it with this one. No special tools or gunsmith work required. This approach lets you keep one suppressor body and swap pistons to match different barrels and calibers in your rotation—a smart move if you're running suppressors across multiple platforms.
| Thread Pitch | M13.5x1 Left Hand |
| Material | 17-4 Heat Treated Stainless Steel |

This piston has an M13.5x1 left-hand thread. It will only fit barrels threaded to that exact specification. Verify your barrel's thread pitch and direction before purchase—using the wrong thread pattern can result in unsafe installation.
Yes. The supplier notes that this piston is a good choice for converting an SRD45 suppressor body to work on 9mm hosts. Simply swap out the original piston for this one.
You receive the piston only. The suppressor body, user manual, and any other accessories are not included.
Remove your suppressor from the firearm, unscrew or disassemble the suppressor body to access the original piston, swap in this new piston, and reassemble. No special tools are required, but always consult your suppressor's manual for detailed disassembly and reassembly steps.
