Most Helpful Positive Review 9mm conversion barrel
The 9mm conversion barrel was exactly as described. Purchased this for the conversion of my Glock 27 and it fits flawlessly. The entire transaction through Optics Planet was smooth. The delivery was very quick.
Most Helpful Negative Review Gun jamming with new barrel
Upon my first qualification with the new barrel in November 2022 I had no problems. I fired about 200 rounds through it with no problems. Upon my qualification today I had multiple misfeeds and jams. I tried several different magazines and our range officer shot it as well with the same malfunctions...

Lone Wolf & Magpul

by Ed C., Verified Owner from TN, United States Written on January 24, 2026
It took a few weeks to receive, but worth the wait. The Lone Wolf 9mm barrel & Magpul 12 round magazines transformed my Glock 27 gen 3 into a 26. It cycled 115 & 124 gr fmj with no problems. I still like.40 for carry.

Double your caliber options for your Glock with just this and a 9mm mag!

by Rustyvw, Verified Owner from AS, United States Written on August 23, 2025
I do not trust unbranded Glock conversion barrels so it is worth it to me to buy the Lone Wolf ones as their stuff is flawless. It slipped right in and is a quality item. Fitment and materials are spot on. I just added an OEM 9mm mag and I have a more comfortable carry piece when needed. Price is much higher than generic ones but I know this brand is trustworthy and can be counted on in an emergency.
Pros:
  • Finish and fitment are tops!
Cons:
  • Not cheap.
Best Used for:
  • Safe precise caliber conversion.
Would recommend: Yes

My second Lone Wolf Arms barrel. . .

by Rob, from PA, United States Written on February 25, 2024
. . .because I liked the first one I bought so much! I bought this 9mm conversion barrel after buying a stainless steel.357 conversion from Lone Wolf a few years ago-- now I have a single handgun (Glock 27) that shoots 3 calibers just by changing the barrel. NOTE: When I first got this barrel I noted a very dull, inconsistent finish inside the barrel, in contrast to the mirror-like finish on my other stainless Lone Wolf barrel-- this concerned me a little but I decided to shoot it anyway, putting 50 rounds of reloads through it. Upon cleaning it again, I noticed that the inside now had the mirror finish I was expecting. So, if you initially see a dull finish in the barrel, just know it'll get better with use. The finish on the exterior was perfect. I shot fifty rounds with perfect operation without having to change the ejector. Hope this helps. -- Rob
Pros:
  • Simple barrel swap to change calibers.
  • Nice finish / graphics
  • Reliable operation in a G27
Cons:
  • None
