David K from United States, AZ Public Profile

I installed the barrel in my 30+ year old Gen2 Glock 23, loaded a Magpul 21 round magazine with 124gr Winchester Valor (NATO), and the gun ran perfectly. Accuracy was every bit as good as the factory .40 cal configuration. No ejector/extractor changes needed. Ejection pattern changed to almost vertical, but that's expected with a conversion and has nothing to do with the barrel. I ran 5 more mags doing both slow-fire and rapid-fire with zero failures.

Fit and finish is excellent. Slide lockup is a little closer tolerance than factory which was nice to see. I wasn't able to test with a suppressor, but threading looks clean so I would not expect any problems. Overall, extremely happy with both function and value. I need to run several hundred more rounds for full confidence, but barring any surprises, I would definitely recommend.
