In this video accuracy between the lone wolf and factory barrel is drastic. Difference of feet in accuracy at 50 yards. This guy is a hardcore Glock fan so i dont think he trying to knock them in any way. It would have been nice if he compared the two barrels using standard loads. Is this due to the use of the hard cast bullets or is this consisent with all ammo. I've read varying reports from there is no difference in accuracy between the factory barrel and aftermarket to a significant increase when dropping in a lone wolf, kkm, etc. I've read many post on here about how accurate the glock 20 is that with the factory barrel or an aftermarket. Would like some definative answers based on actual experience using the two. Thanks in advance!

Go to the arfcom reloading forum and make a dupe post. Majority of Glock guys shooting lead use Storm Lake, Lone Wolf, KKM, etc. Barsto makes an aftermarket Glock barrel.
Anyways, we've got a few die hard Glock owners who've mastered the process of casting hard lead and use factory barrels to shoot their lead. They're faithful to cleaning after use, not allowing or shooting with lead build-up. Polygonal bores and lead aren't as accurate as traditional rifling, no secret to this fact. The guys shooting lead through Glock barrels accept this as fact, following up with, " accuracy from Glock barrel is good enough for me." I've shot my Glocks with jacketed, using both Glock barrels and KKM barrels. Intend to fit a Barsto to my OD Green G19, why ? Group performance. Now flip that coin. Polygonal bores create more pressure, more pressure. Not peak, but barrel pressure equates to velocity. Debate Glock barrel vs Aftermarket, depends who you ask, most state a good aftermarket is more accurate, enough to make a switch for some ? Arguable. 
I'm a group shooter, my idea of fun isn't filling an A zone on the run. Yea, its important to train but if you shoot a lot, like a lot of guys shooting tons of bullets and shooting a lot with lead don't need to train every single range trip, not with round counts that add to five digits a year. We go to have fun, laugh a lot with others, aim small and shoot small. Most of us would respond with yes, of course traditional riflings more accurate. This said, we always get those who state their Glock barrels are accurate. Problem is, statements aren't followed with math or visual. When we objectively compare with those who truly want to see the differences, aftermarkets like KKM out group Glock factory barrels. Degrees of accuracy vary by individual definition. The crowd I shoot with measure accuracy by the inch, not by zone. Regards, dc. |
| after the 2009 Ft Benning 3 gun match, I switched from a G17 to a G34 to be used for both 3gun and USPSA Limited minor competition....for most local matches targets were no more than 20m and I got acceptable accuracy with box store 115grain bullets... unlike 1911Smith, most of my shooting is the on the move stuff, so I'll take an "A" and a "C" for score....for the 2010 Ft Benning match I added a Briley match barrel, and overall shot a rather poor match, particularly on longer, more precise pistol stages... returning home, I looked at the accuracy problem, and found that the 115 grain bullets at 30m would barely group 8" offhand... switching to 147s, considerably less....comparing the factory G34 barrel to the Briley... off a rest... the factory barrel produced about a 5" group at 30m, the Briley about an inch smaller with factory 147s... with my Delta Precision/WSF handloads at about 935fps, slightly less...the groups did not really start to open up until past 25m |

25 yards is the tipping point for glocks - combat accuracy wise. To 25 I can keep them in under four inch groups under three on a good day. But at fifty yards you are lucky to find groups of under nine inches. For long range accuracy revolvers and 1911's are the way to go.
Due to my clubs safety issues when we shoot steel matches we have to use lead. Commercial bought cast bullets in factory glock barrel works for me- longest shot is about 20 yards on our range and no smaller than a six inch plate no problems with lead. A few passes with a brass brush after every 100 rounds or so is all the bore needs. The no lead in glocks thing is way over blown. |
