Badger....... At least you're trying....
There are a lot of resources out here (some linked in this thread).... I think this thread has run its course... Glocks don't all shoot high.
You are apparently shooting high with yours though...
I can't lock threads in this sub-forum, but I am out of this one....... After reading through the material available on efficient defensive shooting skill development, feel free to start another thread on the training options in the Defensive area...
