Have you heard about the new Glock shortened 45 round? A shortened 45 round to function in a 9mm sized frame for people with smaller hands? Sounds like a bad idea to me, but what do I know. Gaston Glock hasen't made many mistakes so far. I really don't get it though, the 45 acp has just enough penetration. A weaker round doesn't make sense. Just go to a 40. Maybe Glock wants it's own round. They put 40 auto on their 40 S & W semi autos and 357 auto on 357 Sig autos.
