One of the best aftermarket barrels you can buy - Lantac 01GBG19NTHSS 9INE Glock 19 9mm Luger 4.01" Stainless Steel Fluted

Absolutely love this barrel. People say “I never notice an accuracy increase with aftermarket barrels”… it’s because either they don’t shoot enough, or they don’t shoot far enough. I’ve noticed with this barrel and several others I no longer have to worry about hold over/under At 25yards. Did a simple test stock barrel at 25yards with my red dot is approx a 2-4inch hold over, however with the Lantac POA is POI. There is NO hold over/under st the exact same distance and I LOVE that. I’ve tested this several times in several different glocks and this barrel is fantastic. High quality, looks beautiful, highly recommend.
