Most Helpful Positive Review Great for my M18
Picked this barrel up to drop into my M18 for a suppressor host. The barrel drops right it without having to remove the LCI. It does stick out a little further than I expected to as a compact barrel, but who’s really going to complain about a little extra barrel?

Great fit vs the stock barrel

by Jonny, Verified Owner from VA, United States Written on September 28, 2024
I was looking for a threaded barrel to fit my Harrington Arms comp and this barrel just fulfilled that. It looks amazing, threaded cut perfectly, lots of compliments on the look. Adds a little flare of style and well built. I got this because it's the 4.6 which is required to have a flush fit with the compact slide and full size grip.
Pros:
  • Build quality
Cons:
  • None
Best Used for:
  • Adding comp
Would recommend: Yes

Awful Quality

by Spencer, Verified Owner from TX, United States Written on January 21, 2024
This my 3rd review update:
After firing 500 rounds through this barrel the GGP slide has rubbed off the finish completely and bare metal is showing. The barrel is accurate however the quality is absolute trash. The only upside to this is I got a really good discount. I’ve been fighting with GGP’s customer service for weeks now and I’m just hoping I can get a refund or possibly a replacement. I have my doubts.
Pros:
  • None
Cons:
  • high price
  • poor quality
  • awful quality control
  • bare metal showing after 500 rounds
Best Used for:
  • nothing
Would recommend: No

update from previous review

by Spencer, Verified Owner from TX, United States Written on January 5, 2024
Barrel looks great and it is a bit more accurate than the original however, the quality of this product is awful. I shot less than 200 rounds through this barrel and the finish is almost completely ruined by the slide literally grinding against the barrel. I have the Version 2 GGP slide for a P320 compact with the GGP threaded barrel and the quality is just awful. They clearly didn’t not take the time to make sure the tolerance was right. There is bare metal showing on the inside of my slide and the barrel is almost showing metal with less than 200 rounds. For the price of this upgrade it has no turned into a Downgrade.
Pros:
  • Looks great
Cons:
  • Not designed for other GGP products
  • finish is rubbing off with less than 200 rounds
  • price is way too high for awful quality
Best Used for:
  • stock Sig products
Would recommend: No
