[Brownells Glock Barrels?]

Little bit of an aged thread. But Brownells barrels are manufactured for them by a VERY reputable barrel manufacturer, who also makes barrels for some of the biggest aftermarket Glock companies. Comparing them to a factory Gen4 and Gen5 barrel they destroy them in accuracy from my experience. Now I have noticed they recently started putting out ones that are laser etched and aesthetically look different along the lines of brand marking. So I don’t know if they changed to a different manufacturer as the old ones were laser engraved on the left side compared to etched on the top of the chamber.

Mine acquires some carbon but nothing I would complain about. However, I have upwards of 7-8k through mine without being cleaned. 

[147gr 9mm IbejiHeads loadout]

Im sort of new to IDPA shooting. Joined back in 2013 and shot maybe 3-5 matches and work scheduling didn’t allow me to make matches but now just started back up last month. I’m shooting a Glock 17 Gen 5 in carry optics and have someone willing to reload for me. I have acquired a pack of 1000 IbejiHeads 147gr. flat point coated bullets to load and basically have all the 9mm once fired brass I can get from my police academy. Has anyone loaded these specific bullets with Titegroup? If so, what is your load out and COL for 125-130 PF.

 

From some research I was considering something like below and test from there for an acceptable PF and see how they shoot:

3.2 - 3.4gr Titegroup

1.130 - 1.135 COL, .377 crimp
