Otter Creek Labs Lithium 9 Suppressor Details
The Otter Creek Labs Lithium 9 is purpose-built to dominate the PCC and SMG category with one of the best weight-to-suppression ratios of any 9mm silencer. At just over 10 ounces, this all-titanium suppressor balances featherweight handling with deep, clean tone that makes range sessions and tactical runs far more enjoyable.
Designed with internal venting to control port pop in direct blowback systems, the Lithium 9 keeps gas and noise manageable even on aggressive setups. Its HUB 1.375×24 mount makes it compatible with today’s most popular direct-thread and QD systems, so you can tailor the fit to carbines, AR-Vs, MPX-style hosts, or classic subguns. Rated for 9mm +P ammunition, it shrugs off abuse while keeping recoil light and manageable.
Whether you’re training indoors, shooting suppressed matches, or running a truck gun, the Lithium 9 offers a perfect mix of versatility, sound suppression, and lightweight performance.

First suppressor I purchased and I couldn’t be happier with it.
William L –
Perfect can for a PCC and works amazing on 300BLK as well. Love the aesthetics – it’s basically a video game suppressor!

The lithium 9 by OCL is a phenomenal 9mm suppressor. Having thrown it on some pistols and some PCCs, it eats everything I shoot through it. I love how simple it looks and you can tell it’s made well. OCL is fantastic. Highly recommend if you’re looking for a versatile 9mm can.

Solid can, well built and extremely light. Paired it with the SilencerCo ASR adapter makes it perfect for my setups.
Also a small business from here in Kentucky, proud to support our neighbors!

I need to start off by saying I bought this for the express use of a custom ultralight 300 blackout subs and SUPERS. One of the only cans I’ve seen this light that are rated for supers. I’m tired of waiting for the CGS mod9x to be released. I didn’t need all the fancy mounting solutions and other jazzy stuff, just a dependable, effective product. This fit the bill fantastically at a cheaper point than most others. I had to buy a rearden Zro in 5/8×24, woulda been nice if it was included, but I understand. Suppression is not equal to my Hyperion, but that wasn’t the goal. Suppression was very very good though. Absolutely hearing safe with a nice tone. On my subs, I hear a hiss and the drop of the firing pin, that’s it. I have developed several special loads for 300blk that are Hollywood quiet. This can handles them fabulously. I can’t say enough good things about this simple, effective and super lightweight suppressor. I’m not sure how it would hold up the the rigors of combat, but that’s not its purpose for me. I did check the point of impact shift by screwing off and on, no measurable movement in groups on my rifle. Now for someone wanting to put this on a 9mm pcc, or any 9 for that matter, I think this would fit the bill nicely as well.

Solid can, super light. sounds good on a 5 5/8 MPX and on a Barrett MRAD in 6.5 7prc and 308 as well.
Daniel M –
Very nice to use and shoot
Jimmy Dever –
Very lightweight and well made, welds and finish are very nice. Put about 300 rounds through it using the resilient titanium hub tri lug on my hk sp5k pdw without issue. Compared to my obsidian 45 in short config they sounded the same. Perfect can for any mp5 variants.
Donald T –
It’s perfect for MP5 and very good quality.
Matthew K –
Great can, i highly recommend OCL products. Runs 165gr 9mm subs great with thr YHM tri-lug adapter
Jesse T –
Light weight and suppresses well, HUB makes it simple to swap to my pistol. The OCL gang rocks. I’ve only used on in 10 degree weather so I’m sure a few of my 8″ SBR shots would have been subsonic in warmer weather. So far a great purchase.
Mack Cooper –
Love it great noise reduction I can take my grand kids to the range and not worry about hurting their ears
Jacob P –
Awesome silencer. Light, quiet, and durable. Would absolutely purchase again.
William W –
The guys at Otter Creek lab are great, purchased this and put it on my pcc, ran great. Picked up a piston booster from the OCL website for a discount since I bought this. Great customer service so far and great products.
Matt M –
Great quality and welds (coming from a welder and machinist) can is laughably quiet with 9mm subs on my beretta (even runs without a booster because its so light) Quieter than my YHM ResK on 300blk, and far FAR lighter. I will likely have more Otters in my stable going forward.
Timothy P –
Super lightweight and does a great job on my MPX K. Works perfect with the rearden r2s
Jason C –
The Ottercreek Lithium 9 is high quality and affordable.
Joshua M –
Awesome suppressor! Super light but high quality. I have a couple OCL cans and they make a great product backed by excellent service.
I have it on my 9mm Banshee. It runs flawlessly and sounds great.
I haven’t tried it on a handgun yet because it does not come with a piston/booster which is a little disappointing, but I am very happy with it.
Richard H –
This van is everything I needed iit yo be. I’m using it on a PCC and this suppressor makes this gun shoot quiet and and reliable. I also tucked this can in the hand guard and looks and fits incredibly.
