I've spent a lot of time and money on aftermarket barrels. I've never found any of them to be as accurate as OEM, and definitely not more accurate. I know I'm just some random dude commenting on a gun forum but OEM is very accurate. Link to comment Share on other sites More sharing options...

The profile of the ACME 145’s and 135’s load easily in my Gen 5. I prefer the 135’s and load them to 1.125. Crazy accurate so I didn’t mess with the OAL. But could load a little longer.

rowdyb Posted May 28, 2019 Share Posted May 28, 2019 in a gen 3 g34 i had a barsto barrel. it definitely had a "shorter chamber" and all around was much much tighter in tolerance. it had to be hand fit at the hood where it locks up into the slide. that barrel was very very accurate and a noticeable improvement over stock, even with my limited skill level at the time. but what killed it was how dang picky it was about ammo. you HAD to use the barrel as your case gauge to be certain rounds would chamber. so i stopped using that barrel and sold it. i now have two gen 5 g34 and a gen 5 g17. my "cz length" loads work just fine in them. i also shoot just 147 grain of different profiles, either plated or jacketed.

thehudge Posted May 31, 2019 Author Share Posted May 31, 2019 Truncated cone, round nose, round nose flat point, the ogive is different even on different round nose designs. We have settled on Xtreme 165gr (9mm) round nose plated. Loaded to the same oal as Blue Bullet 147gr Round nose (1.150) the 165gr will plunk in both the Gen5 oem and the KMM barrel but the 147's will not plunk in the Gen5 oem barrel. The same load in my 4.7 inch Sig p320 barrel vs the 5 inch KKM barrel in the G34 gen5; the KKM barrel runs 50fps faster. We have not determined which barrel is more accurate.

TCB Posted June 4, 2019 Share Posted June 4, 2019 (edited) Any issues with moly coated bullets in Gen 5 Glock barrels? My Agency is going to them and I just picked up a couple to start playing with. Currently using the same 147gr Xtreme over N320 I loaded for my H&K’s with no issues. Was planning on trying a box of Bear Creek 147gr that a buddy has...

TCB Posted June 8, 2019 Share Posted June 8, 2019 Well, The Bear Creek 147gr flat nose loaded out to 1.15 plunk and spin with no issues in my Gen 5’s...didn’t bother seeing if I could go longer as 1.15 seems like a good OAL for 9mm. Link to comment Share on other sites More sharing options...
