Double Diamond 9mm Conversion Barrels for Glock
Ratings & Reviews
Great barrel and very accurate to convert to 9mm
by Big Jer
Received one of the last generation barrels recently for my Glock 23. What a difference. The .40 barrel would throw rounds in a varied grouping but once I got this sighted in, shoots a very nice group at 25 feet. Would recommend highly. Sidenote, threaded DOES come with a thread protector already. Add a little blue loctite to keep it in place.
Double Diamond Perfection
600 rounds through it so far and zero problems. I did replace the extractor and ejector with Glock 19 oem parts. No FTF or FTE problems at all. Also no problem with brass hitting me in the face. Beautiful fit and finish. Thank you Glockstore!
Got to take this for a walk at charity event shoot for 4 days.
Threw this in my G22 Gen3 and fed it S&B 115gn fmj. The barrel was machined true, could ragged hole at 7yds. Good enough for my eyes.
Downside: In 800 rounds I had 14 Type 3s. Could be a lot of things including the ammo, however, my G19 Gen2 ate the same amount of the same ammo and got 1 Type 3. In this case, maybe not the ammo. Could have been tired hands.
Take Away: I wouldn't use it for carry, but for range work I think it's awesome. Besides, Type 3s are my favorite. Finger magic.
Buy with confidence great product
I'm completely satisfied with this conversion barrel and with the CustomerService I received from the glock store. I waited for a sale and got the barrel for 116 bucks with free shipping and after ordering I live chatted with Conor An he told me it ship towards the end of the week I ordered it on a Tuesday it shipped on Thursday and got it Friday... since installing (in my glock 35 G4) i have put about 100 rounds through it no problems great fit and finish and very accurate... I have nothing negative to say if you are thinking about buying this barrel you wont regret it
Works like a charm.
Since I converted my Glock - 23 from a 40 cal to a 9 mm it works like a charm. At first I had a feed problem because of the new Gen 3 lower but it went away after a few rounds
Fantastic 9mm barrel
Great quality, perfect workmanship. Accuracy on par with Glock factory barrels. As good ( maybe better?) than my Glock 26.
