Sig p365, ultra compact with 10 round capacity, hadn’t been done before.

Any of the suppressor manufacturers.

Ultra long range bolt guns from a variety of manufacturers (notably not Remington, colt, etc).

Several novel application PDW systems (personal defense weapon). B&T, FN, Sig, HK, and others.

Optics have rally stepped up. Always on 8 year battery life 300ft submersible red dot sights from aim point. Crazy precision scopes from vortex, nightforce, a few others.

It’s certainly a hobby that you can spend $100k on really easily exploring a variety of styles of defense and sport shooting.

Glock is a fairly obvious one.

Sig's recent P320 system is another obvious example, where they've completely modularized the fire control group, allowing that to be swapped freely between multiple grips, calibers, and even form factors.

Yeah but that's only made convenient by dumb laws.

Vouched for this as it's a good point for anyone who understands the P320 FCU and the legal framework which inspired its creation.

The FCU concept would still have value were the legal framework less Byzantine, but its practical benefits would be significantly diminished.

The Glock 17 was introduced 39 years ago, not quite 50 years but still.

It's also worth pointing out that while the manufacturing techniques used by Glock were new the actual design is essentially identical to the browning hi-power.

Materials are an incredibly significant element of design. Some of the most significant innovations of the AR-15 were in terms of materials. The Hi-Power also uses a single-action hammer rather than a striker, so I'm not sure how the striker-fired Glock is "essentially identical" to it.

For the unfamiliar, the Heckler & Koch VP70 was the first polymer frame, striker-fired pistol, and predated the Glock by 12 years.

BHP is hammer-fired, Glock safe-action is striker-fired.

Thoughts on Kel Tec?
