If you're looking for future product ideas, I wish someone would visit the past.
2 or 3 decades ago someone (I don't remember who but I sure remember handling the frame) was making a thin, aluminum 1911 frame without any cutouts on the sides and without a cutout for the grip safety. You could run it naked, without separate grip panels, for an extremely thin, light piece. The lack of a grip safety was also a huge bonus for guys like me with fatty hands who often failed to actuate the safety properly; this was back in the days before the "memory bump" or "speed bump" came into fashion. I still prefer a backstrap without moving parts.
Make that and I'll buy one.
Not sure if this is what you are referring to, but here is a patent.
Patent USD345002 - Combined frame with grip for handguns - Google Patents
I think that one of the patent holders is now Infinity Firearms
They offer a very different take on the competition 1911, where the bottom half of the frame (grip, triggerguard, etc.) is a separate piece that bolts on to the upper frame. So no grip panels.
Interesting idea.
Their custom frames,
Grip section......
Here is one with a cut out in the grip section so you can see through the magazine well.
Sorry to dive a bit off course on this, but there is a lot of room for folks like the OP who think outside the box to produce some great stuff in the future. Maybe some ideas to help the creative juices flow.
