I don't know. The first thing most Glock shooters do is change sights (something about cheap plastic sights that turns them off I guess) and replace trigger parts to get a decent but still mushy trigger pull.
I don't suppose in your observations you noted the nember of shooters who were shooting pistols they didn't like the fit of, that couldn't hit the target with their first round. Seems to me to be a rather difficult question to ask but you seem to have at least addressed those with guns thta fit comfortable in their hands.
As to proper fit you might be surprised how quickly one can acquire a decent sight picture quickly with a pistol that fits the hand just right. My M&P with the small grip insert allows me to drive my hand higher into the grip then teh large insert and the sights come to eye so much quicker.
If you think a light smooth trigger doesn't aid in accurate shooting you obviously haven't spent much time around Bullseye shooters or at the other end of the spectrum watched RCMP officers attempting qualify with their service pistols when shooting from 25 yards. You don't see many of the DAO S&W pistols used by the RCMP at Bullseye competitions and almost as few at IPSC matches. Come to think of it I haven't seen to many Glocks shooting Standard Division in IPSC either. I guess IPSC shooters haven't read your posts suggesting great triggers have little to do with accuracy.

Sorry for the late reply Bob, this thread got buried and I missed your response.
The factory plastic sights are usable but far from ideal, I agree that steel sights are good change from the factory ones. Note also, that the factory plastic sights are not tritium night sights. If you expect to shoot in low light/no light conditions you must have tritium sights.
As far as "fit" goes. I don't believe I've ever met anyone who admitted their pistol didn't "fit" right and attributed their poor marksmanship to said "fit". Regardless, it seems many strongly believe that "fit" is the most important factor and many have echoed that "fit" is what they looked for prior to purchasing a pistol. That being the norm, it would be safe to say that most are shooting a pistol that "fits" their hand. Again, with so many running a pistol with the proper "fit" I don't see too many who are capable of first round hits in a timely fashion.
acquiring a proper sight picture has more to do with ones grip than the "fit" of the pistol. If you watch any of the "instructional videos" online from the pros, you will see that regardless of what pistol they demonstrate with, their ability to make hits is unaltered. Obviously if you spend the majority of your time on one system more than the others your performance will reflect that. However, the fundamentals of handgun marksmanship are 100% transferable. For those who understand them, the results from system to system are remarkably similar.
I won't disagree that smooth light triggers don't aid in accuracy as they do. What many fail to take into account is the shooters ability. A smooth and light trigger is only as effective as the individual pulling it, or in many cases slapping or yanking it. That being said, the stock triggers on most pistols are more than adequate for the majority of disciplines. One should also keep in mind that the majority of pistols(especially those in production division) are service pistols, intended first and foremost to be reliable when defending life.
The RCMP S&W's have the worst trigger pull I have ever had the opportunity to experience(ok maybe not, the Hungarian FEG hi power copy was worse). I've also witnessed several folks consistently make hits with the same pistol and observed others with high end 1911's fail to hit the target. The altered variable in this situation that makes the difference is the shooter. With some exceptions as noted above, the factory triggers on pistols is not the culprit of missed shots.
As for the lack of Glocks in IPSC, I couldn't tell you. I suspect it is due to the belief that Glocks have bad triggers and thus would require trigger work which means they would not qualify for Standard division. I suspect it also has to do with the fact that many feel that Glocks are ugly and uncool. No one wants to shoot a plain, ugly black pistol that isn't respected.
The bullseye crowd is a different breed. The entire discipline is contrary to what a service pistol is designed and intended for. I'm sure most service pistols are capable of bullseye level accuracy, but the sights usually are not. The lack of Glocks or any other service pistol in bullseye is simply a case of the wrong tool for the wrong job.
