Something my buddy and I discussed awhile back is the dearth of firearm innovation for the civilian market.
Certainly there have been design improvements over time, but our focus was on truly ground-breaking technologies that would change the entire industry.
Once the ebil gun-loons settled on...
1. Centerfire metallic cartridges.
2. Smokeless powder(nitro-cellulose based).
3. Necked casings.
We kinda hit a wall in my view. Like I said, many improvements have been made to both guns and their ammunition but what was the last thing that impacted the entire industry?
The Mauser 98 bolt action design is probably still the best there is and semi-auto handguns have become smaller to compliment CCW laws sweeping the nation over the last few decades. But outside of the military, what was the last thing that changed everything.
More importantly, what do you THINK will be the next big breakthough?
One idea I had was a handgun which had its barrel directly in line with the center of your wrist and arm so that recoil would be directed straight rearward, into your shoulder, instead of your wrist being a pivot point for upward rotation. This would keep you on target for quick follow up shots.
Something like the palm pistol as far as alignment, but with more modern ergonomics and capacity.
