I wasn't sure if these would do what I needed, and I needed three to find out. This was the least expensive way to do that.I purchased them for my .40 S&W Kel-Tec Sub-2000 Gen 2. I removed the front sight and wanted something to cover the threads. Three of these perfectly covered all the threads right to the end of the barrel. I haven't shot it yet so hopefully they stay on tight. ### ⭐⭐⭐⭐ Exactly the product it describes, but make sure you don't already have one coming... *by M***T on March 28, 2015* Exactly as described, I use on .40 Glock 22 Gen 4 with Stormlake threaded barrel, comes a bit loose after ~250 rounds but hey, it's better than pinning it in place since it is really a placeholder. Would like to see a nut/wrench formation for tighter fit but does the job it is supposed to do and for a good price.That being said, I assume you have bought a threaded barrel- make sure you get that first and see if it comes with one of these as I bought both together from the same site at the same time (here) and it turns out Stormlake gave me one of these for free with the barrel, so.... ### ⭐⭐⭐ I've had better but free 2 day shipping...so... *by A***R on May 4, 2016* Kinda flashy on a black gun but thats why I bought it. I've probably lost 5 black thread protectors over a 3 year period. Hopefully I'll be able to see it when it drops in the grass(and it will). The reason I give it 3 stars is because the inner threads had alot of burrs that had to be removed with a small wire brush. When it first arrived I went to install it without checking the threads and It was as if the threads were full of sand. Very gritty turn. Never had that issue with the 5 previous protectors from hk parts or aac. It's good now but like all the rest it loosens when firing unsuppressed for extended periods of time. Once I lose this one I'll probably get the silencerco protector because it has an o-ring inside. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/13722635-stainless-thread-cap-protector-40-and-10mm-9-16x24-usa](https://www.desertcart.be/products/13722635-stainless-thread-cap-protector-40-and-10mm-9-16x24-usa) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-10-10*
