Most Helpful Positive Review 20L/40 40 S&W
Excellent quality! Fits my Glock 40 mos perfectly. Tight lock up. The external flutes make it easy to tell which barrel is in the weapon. Good snug fully supported chamber. Shooting the 40 S &W out of the G40 platform is a blast!
Most Helpful Negative Review Wolf barrel marked to fit a g 20 and a g 40 glock 10mm
This barrel does not fit the Glock G40 as advertised. When I called Wolf Barrels about it, I was told that this barrel is for a G-20. It is marked as fitting a g 2o and a g 40 however the shroud just ahead of the chamber is too long to allow the g 40 slide to completely close and go in battery

10MM GLOCKSF

by todd, from WI, United States Written on March 10, 2023
JUST RECIEVED THE BARREL AND PUT 5 ROUNDS IN IT FOR RAPID FIRE AND IT SHOT GREAT. THEN PUT 5 ROUNDS IN FOR AN ACCURACY TEST AND HIT A SOFT BALL AT 45YDS OPEN SIGHTS AND IM A TERRIBLE PISTAL SHOT. SO VERY HAPPY WITH MY PURCHASE

Excellent Drop In Barrel

by Robert Dare, Verified Owner from MT, United States Written on December 14, 2022
Dropped right into my G40 10mm with no issues. The barrel for my G20 is also quite good too. This should be very similar.
I do wish the coating was slightly more durable to scratching.
I also wish Lone Wolf would partner with Robar for an NP3 coated version for additional cost. Maybe a special release batch.
Pros:
  • good price
  • Drop In
  • Increased accuracy
Cons:
  • Availability can be spotty
  • Coating on barrel could be slightly better
Best Used for:
  • Hunting or home defense
  • Hardcast ammunition and JHP
Would recommend: Yes

Fit and finish are perfect

by Jethro, from IN, United States Written on April 11, 2022
I transformed my 10mm into a 40 cal. 10mm ammo $39.99 40 Cal $ 24.99 and easier to find. Many of the 10mm target loads are just barley hotter than a 40 S&W so why pay the premium. Barrel is nice I am going to get other barrels for my other Glocks.

Adds versatility

by MHD, from MI, United States Written on April 8, 2022
Being able to shoot less expensive ammo with greater availability is a real plus for additional practice and training. Less recoil but same point of impact out to 25 yards is another big advantage. Barrel is a precise fit and no issues with feeding 40 as opposed to 10MM (no issues feeding that either) Great product
Pros:
  • Fit, function, expense, versatility
Cons:
  • All the 40 S&W I had stockpiled is disappearing
Best Used for:
  • Practice, defense, coyotes
Would recommend: Yes

Works as intended

by BigMike, Verified Owner from NC, United States Written on February 24, 2022
Threw this barrel in my Glock 40 gen 4 and it is definitely drop in ready. No magazine switch or any other changes. Occasional hangup on the feed ramp but that’s was expected with how flat nosed 40 is. Well worth the money to save money on buying 10mm
Pros:
  • Cost effective conversion
Cons:
  • Occasional (1/50) hangup on the feed ramp which requires slight rechambering of the round
Would recommend: Yes
