What has GG done since the G17? Honestly nothing but shorten this our that part. Great design no doubt but it is just that, a single design.
JMB......Taking away the 1911 (which I personally believe was designed by the Almighty himself and not JMB!) JMB still has this bad boy in his corner among many many others.
This alone rockets him past GG in firearms design. Almost 100 years old and still the king of MGs in todays world.
GG may or may not still have his designs still in use 100 years after their design, JMB has several still in use, and not going anywhere soon.
