Manufacturer claim
- At 4.0" by .875" the Wasp is purpose-built for the Beretta 21a and uses a cutting-edge baffle stack with artificial-environment (wet) technology.
- Monocore, no tool required for disassembly.
- Thompson Machine builds mono-core suppressors engineered for full user serviceability; the company introduced its first suppressor in 1991 and its first Mono-Core suppressor in 1998.
- Standard finish is spun/brushed stainless; a matte black Cerakote finish is available for $50 extra.
