Laser accuracy - OpticsPlanet Exclusive L2D Combat Precision Match Fluted/Threaded Barrel, Glock 19

I'm a pretty proficient pistol shooter. Stock Glock 19 can hold roughly a 2-2.5" group at 25yards. I have a upgraded Glock 19 with a Suarez trigger, and their skeleton striker. I recently acquired a suppressor for pistol calibers and needed a barrel upgrade. I chose the L2D after viewing many brands. The company seems to take pride and it shows by them listing all the specs of the barrel. Could be all smoke and mirrors but to the range I went. I shot the same ammunition as I normally do for range use, Fiocchi 115gr FMJ. I was astonished that my smallest grouping at 25yards was 1 inch. This was not from a ransom rest, all shooter, so variables could play into better or worse accuracy. I shot multiple groups under 2inches that day the best being 1" and the worst being 1.8". No malfunctions within the first 200 rounds of use. No coating wear, thread cap never loosened up. Defiantly worth the investment.
