I just got a brand new LWD conversion barrel for my Gen 3 G23. I had to wait for them to come into stock, so I assume it is of the very most-recent manufacture. I took it to the range for the first time on Thursday for a test run. I fired 100 rds. of Fed. Champion 115 gr. FMJ. I have read that these barrels are extremely accurate, and that they usually function OK, but sometimes have a few feeding problems. However, my experience turned out to be the opposite. In 100 rds, firing in different ways (single-round, double-taps, extended rapid-fire) the gun ran absolutely 100% problem-free. However, accuracy seemed to be terrible. I mean REALLY bad. It seemed to be throwing rounds all over the place. Since I was shooting only steel targets, I don't have measured groups to compare real data. However, I could not hit my long-distance targets that I normally can hit very consistently. I could see rounds striking all-around the targets on the backstop, indicating that it wasn't a POI problem, but rather a serious loose-grouping problem. I don't think ammo was the issue, because that ammo has performed perfectly fine in other guns. Next trip I will bring some paper targets and shoot some groups with both the factory .40 bbl and the LWD 9mm bbl to compare. In the meantime, does anyone have any suggestions as to what the problem may be, or a possible fix? Thanks!
