Because they are blowback operated, the 25 and 28 lose the five points for a locked breech, they also lose another seven points for going down from 9mm to 380. The G25 scores sixty six points, even with a target sight and trigger. The new loaded chamber indicator extractor only adds five more, bringing it to a grand total of seventy-one points. "Missed it by that much" as Secret Agent Smart used to say.
Is there anything that Glock can do? Not much without making a big change in the design. A grip safety or magazine safety would do it, but how could Glock make them available on those two models and not the rest without arrousing the interest of the civil liability lawyers out there? No, any change would have to be implemented across the board, and it isn't possible.
You can see from the chart that Glock won't be bringing in any 22 rimfire models either. A long rifle Glock would score just the same as the 380's, not as big as a 9mm and an unlocked breech. If you want a rimfire Glock, you have to get the upper from a source here in the U.S.
