The Innovative Arms IA-SC9 integrally suppressed CZ Scorpion EVO offers exceptional quietness by porting the barrel to slow supersonic 9mm rounds to subsonic speeds. Testing showed muzzle decibels as low as 121 dB, with action noise often being more prominent. While effective, the HB Industries handguard can get very hot during rapid fire.

Quick Summary

The Innovative Arms IA-SC9 integrally suppressed CZ Scorpion uses a 4.8-inch ported barrel to slow standard 9mm ammo to subsonic speeds. This results in very quiet muzzle reports (121-127 dB), though action noise contributes to higher ear readings (136-141 dB). Pricing starts at $725 for the kit.

Frequently Asked Questions

How does the Innovative Arms IA-SC9 make standard 9mm ammo subsonic?

The IA-SC9 features a unique 4.8-inch ported barrel. These ports bleed off excess gas pressure, slowing down supersonic 115gr and 124gr 9mm rounds to subsonic speeds before they enter the integral suppressor, ensuring quiet operation without specialized ammunition.

What are the decibel levels for the IA-SC9 integrally suppressed Scorpion?

Muzzle decibel readings for the IA-SC9 are very low, measuring 121-123 dB with 158gr subsonic loads and 126-127 dB with 115gr supersonic loads. However, shooter's ear readings are higher, between 136-141 dB, due to action noise and port pop.

What is the price range for the Innovative Arms IA-SC9?

The Innovative Arms IA-SC9 is available as a suppressor/barrel kit starting around $725. A complete firearm configuration can range up to $1750. Remember to factor in the $200 NFA tax stamp for the suppressor.

Does the IA-SC9 require special subsonic ammunition?

No, the IA-SC9 is specifically designed to make standard supersonic 9mm ammunition (like 115gr and 124gr) subsonic through its ported barrel system. This allows for quiet shooting without needing to purchase expensive subsonic rounds.
