I think that the Glock has a combination of features that land it in some kind of mystical sweet spot. I’ve tested pistols with better triggers and pistols that were more accurate in slow fire at longer ranges, but I keep coming back to the Glock.
I suspect that the Glock’s flat sides help orient the pistol in the hand during draws at speed. I got that idea from a post that Darryl wrote about knife handles. A couple of years after I read that post, I went down the HK rabbit hole (P30LS, VP9, VP40, USP). All were more accurate in slow fire at longer ranges and I shot some of my best times and scores on The Test with the VPs. But when I really hit the gas, I was much more likely to throw a flyer—and I mean REALLY throw it—with a VP than with a Glock. Not sure why that is, but I keep coming back to how the flat sides helped to orient the pistol in my hands at an almost subconscious level.
