Tell you what, look up Wilhelm Bubits.
He was a former Glock designer but when he brought his ideas to them, they refused.
Glock does not want to change. Its their call, its their business.
So Wilhelm went off on his own and went to Steyr and built the M and the MxA1 pistols.
Now he works for Caracal and is producing his 3rd gen pistol.
Glock really missed out on this one. But instead gave opportunity to others.
