Weighing just 8.5 ounces, the Blackside adds minimal mass to your handgun, which helps maintain a decent point of aim. Its 7.5-inch length is fairly standard, providing the internal volume needed for good sound reduction without being overly cumbersome. The included thread adapters cover common pistol patterns, meaning it’s often drop-in ready for guns like the Glock 21 or USP 45 with threaded barrels. That said, always verify your specific host’s thread pitch.
Who This Suppressor Is For
This silencer is for the practical shooter. You’re not chasing the absolute quietest decibel rating on the market if it means spending twice as much. You want a reliable tool that makes shooting more comfortable, protects your hearing, and works on several guns you already own. It’s ideal for .45 ACP pistol owners, PCC (Pistol Caliber Carbine) users in .45, or anyone with a 9mm host who appreciates a larger, more durable can. If your priority is maximizing performance per dollar, this is a contender.
Pros & Cons: The Practical Tradeoffs
Pros: The price is the headline. You get a reputable Gemtech product without the steep cost of some titanium or stainless steel models. Being user-serviceable is a huge plus for long-term upkeep. Its multi-caliber capability means one tax stamp covers multiple firearms. The light aluminum build is easy to handle.
Cons: Aluminum isn’t as durable as steel with high round counts or full-auto fire—but for most civilian use, it’s plenty tough. Sound reduction is good, not class-leading. Some all-steel suppressors will be quieter, but they’ll also cost more and weigh more. You’re trading a bit of peak performance for significant savings and lighter weight. Look, that’s a trade many shooters are happy to make.
This product is available at firearms-missouri.com for Missouri residents and nationwide, following all applicable regulations. Remember, an FFL transfer is required for the suppressor itself after your Form 4 is approved by the ATF.
Frequently Asked Questions
Q: What thread pitches does it come with?
A: It includes two direct thread adapters: 1/2×28 (common for 9mm/.40) and .578×28 (common for .45 ACP). This covers the vast majority of popular threaded pistol barrels from brands like Glock, SIG, and HK.
Q: Can I use it on a 9mm AR pistol or carbine?
A: Absolutely. As long as the barrel is threaded 1/2×28, the Blackside is rated for 9mm and will work well on PCCs. Its light weight helps minimize barrel droop on longer setups.
Q: Is it really hearing safe with .45 ACP?
A: With standard 230-grain ammunition, .45 ACP is naturally subsonic, and the Blackside reduces the report to hearing-safe levels. Always use proper hearing protection when possible, but for hunting or defensive use, it provides substantial hearing protection.
