Guys, I'm a long time reloader, since the late 60's.. I do not shoot pistol competition although I have shot about 20 years of competitive benchrest - group shooting..
OK, I hate to even ask this but have to learn somehow.... What is the difference between the 9 major and the standard 9x19.
For instance, can 9 major loads be approached in a Glock with an aftermarket barrel with a supported chamber ? No compensator..
Would appreciate any help in understanding this..
