Mark,
With all due respect. The point you posted regarding drop in barrels that drop in more readily(much like factory) being "less accurate" is BS. If a factory barrel is capable of X size groups, why would an aftermarket barrel of similar fit not perform the same? My G26 shoots no differently than my G17.
The issue with Lone Wolff barrels may not be with all of them. My limited exposure and experience with LW barrels was poor on all models. The suggestion that different brands, weights, styles of ammunition could be to blame is a distinct possibility. However, such issues are not acceptable. A finicky drama queen for a firearm is a waste of time. Again, if the aftermarket barrels are to replicate factory ones with regards to fit, there shouldn't be any issues with any brand, weight, or style of ammunition. My Storm Lake barrel eats everything, just like a factory Glock barrel.

Interesting how people see what they want to see. What I said or meant to say if it didn't come across clearly, was that improvement in accuracy (on barrels) comes primarily through tighter fit and better adherance to tolerance specifications. The tighter the fit and narrow the tolerance allowances the better the accuracy.
If I take 10 Factory Glocks and run them using the same ammo I'll usually get 10 very different levels of accuracy. That's because the tolerances on the slides are quite large and vary quite dramatically from one to the other. The same is true for the factory barrels. Move the barrels from gun to gun and you will get changes in the guns accuracy results.
Factory barrels are usually made intentionally sloppy (not just Glock but other too). This helps the gun feed out of spec ammo, reloads, work when it dirty, etc.. It also make assembly of wide tolerance components easier (slides, etc.). I've seen some factory guns that will shoot with very good accuracy, while others in the same shipment won't group worth #### in m opinion. That's factory standard.
Most people who buy an aftermarket barrel do so to improve the factory accuracy. To do that you trade off reliability since the tighter the gun the more accurate the gun... but it also becomes less reliable as dirt and fit become much more critical. Race guns are never intended to be carry guns... the better you are at one end the worse you are at the other.
The best barrels are oversize barrels... intentionally made NOT to drop-in but to be hand fit by a gunsmith... these give great results... they are very expensive and they shoot great... but they are finicky and essentially it's a handbuilt gun... each is unique and barrels don't swap from one frame to another.
Lone Wolf, Storm Lake, etc. try to find a happy medium with their "drop-in" barrels. BarSto in fact calls their barrels "semi-drop-in" because they very rarely will drop in with out fitting being required.
None of these companies are trying to duplicate the factory barrel... why would they... customers who buy the aftermarket barrel usually do so to improve what they have not replace it with the same thing.
Your suggestion that "your Glock 17 shoots as well as your Glock 26" is interesting. How do you know it shoots as well? Have you actually tested them side by side... truly tested them? Not the BS off-hand shoot a few rounds from each and then make your pronouncement. That's crap.
Have you put the two guns into a proper Ransom Rest type fixture... locked them down and using identical samplings of ammunition... test fired a set series (6 to 10 shots) at a fixed distance of 25 yards on an indoor range eliminating wind, etc. as outside influences. Then after several such series of firings by both guns compared the results to see if in fact they both demonstrate the same accuracy and consistency?" Then repeated the process with several different types of ammunition and recomparing to see if ammunition improved or decreased the accuracy on either barrel?
I would suggest to you that there is a difference in the barrels and the guns... you've just never properly tested to see.
I can tell you that I've done extensive testing with BarSto barrels, Storm Lake and others... when properly done this testing can be a real eye opener. Granted, most shooters don't need and aren't expecting the type of accuracy I'm talking about... and that fine... but I can tell you that I've only once ever seen (and once more heard about) a factory Glock barrel that would shoot the kinds of targets that match grade aftermarket barrels can produce... and in both instances those guns didn't come from Glock that way... they were created by sampling many guns to find the perfect fit between factory slide and factory barrel... it also took a lot of luck to even find that perfect fit.
I test fire Lone Wolf and Storm Lake barrels all of the time for customer guns... they work very well and in 99.9% of cases fire any factory ammo without issue. Both have tight chambers and won't fire even factory reloads (at least not for me) but what can I say... that's just me.
The point I tried to make for you initiatlly is that lots of things can cause a barrel not to work properly in a gun... including improper installation... or flaws. It's just interesting that you seem to be one of a small number of users who experienced an issue so I was suggesting it might have been caused by something other than the barrel itself.
If you think my comments are BS then that's your right... everyone is entitled to their opinion.
