M&P 9 M2.0 (4.25″) Drop In Ultra Match Barrels


(40 customer reviews)


Blacklist Industries Ultra Match Barrels are some of the most precise match grade barrels in the industry and come fully equipped with our NO BULLSHIT LIFETIME WARRANTY. Each unit is precision machined from certified 416R stainless steel for superior strength, longevity, and durability. Critical tolerance requirements and multiple quality-control checks, along with an advanced broach rifling process guarantee outstanding accuracy from each and every barrel produced. 

The strategic advancements in Blacklist’s design provide benefits such as a tighter lock up and significantly better fitment, while also achieving a substantial increase in accuracy in comparison to a stock/factory barrel. The propriety fully supported chamber makes Blacklist barrels compatible with all bullet materials and +P ammunition. This feature reduces the risk of dangerous pressure spikes that are commonly found in stock/factory barrels.  

The barrel also features a recessed crown at the muzzle. The recessed crown preserves the barrel’s outstanding accuracy by preventing the edge of the rifling from being exposed or damaged in any way that can affect the rotation/spin of the bullet. Eight column flutes are added at safe depths which provide a custom look and finish to the barrels. This is a replacement/drop-in barrel, no gunsmithing required!

    So glad I took the leap and bought this barrel. The accuracy is stupendous, you can feel the tight tolerance. I enjoy shooting my 2.0 more now. I would recommend this to anybody that shoots.

    Holy hot tits did this barrel make me finally love my 2.0. The factory barrel begins unlocking way too soon causing a lack in accuracy. Took the chance on this barrel and shot fist sized groups at 25yds all day with ease. Even with handling my pistol I can feel the tighter tolerances. 100% function in over 300 rounds. I’m writing this review in the parking lot of my shooting range that’s how excited I was that this barrel works. Don’t think, buy it.

    Great service, received my barrel in only 4 days. But the best part of my experience with BLACKLIST, is the accuracy of the barrel. Due to COVID-19 virus, I have only been able to make it to range one time, and I was extremely impressed with the 5 shot 1 1/2 in group at 10 yards. also, I also was impressed with the quality and excellent workmanship. The barrel fit perfectly and required no modifications on my part. If you are thinking about an after market barrel, don’t hesitate, it is worth every penny.

    I really like the stainless finish barrel as far as aesthetics go. As far as a “match barrel” I did not see any improvement in accuracy from a rest. I also noticed the fitment was not very well to the slide on the hood as I get a lot of powder coming up. Maybe it was just the barrel that I ordered but that is my observation after 500 rounds.

  5. Mark (verified owner)

    At the range, these barrels command admiration and respect. But, in addition to the prestige factor, they just happen to be beyond accurate! This is my 3rd one and I’m saving up to put one on my G43…

    This was my second Blacklist barrel for the S&W M&P9 full size but this time it was the threaded barrel. The fit and finish is superb and I was getting 3 in groups at 20 yards.both barrels meet that. Can’t ask for better. Will buy again.
