P365 fcu to work in a P320 sized gun. I have been thinking about this lately and think it would be a great hit. I prefer the trigger pull more of the P365 compared to the P320. I understand the P365 fcu is stamped and not milled but I think they would have a hit for something that could use P320 grip modules and mags.

P365-FUSE

I mean, according to the specs this is almost a "true full-size" just a little smaller and lighter, but barely.

But I have to say, if it doesn't have to be a Sig, the Springfield Echelon is really great and only weighs ~1oz more than the P365 Fuse.

I feel like eventually they need to do something with the 320 even if the discontinue it.
Is there any particular reason why they can't adapt the 365 design to work in a 320?
Call it the 325 FCU. Now with fewer uncommanded discharges.

All you save is the grip, mags, and barrel at that point.

But that could be a good thing for those with a bunch of P320 mags and prefer that size.

Not familiar with the product, just know it is exists...

Transform your SIG Sauer® P365 XMACRO / TACOPS / FUSE into something wild with our 6511X Brass Widebody Grip Sleeve. It installs with no permanent modifications; just remove your existing backstrap and slide this part on. When combined with the ported and compensated FDEZ WERX™ Complete Fuse 4.3? Upper Assembly and a Maple Leaf Firearms Optic Adapter Plate (allowing one to mount a Trijicon SRO or Holosun 507COMP) the resulting build can easily hang with the highest performing competition pistols on the market.

Why wouldn't they just make a new grip module (probably would want to be aluminum or steel) and just use a common grip pattern (1911, CZ 75, Browning Hi Power, etc.) and grips kind of like on the sharp bros modules? Isn't the point of these FCU guns kind of that you don't have to mount some kind of sleeve through the backstrap??

Never mind all that.  I want a DAO 938 that takes P365 magazines.

They tried that.  It didn't sell.

Neat idea, but it wouldn't do anything to solve the world's worst firing pin block design stuck in the 320 striker/slide.

Geez man, Sig has 4000 models and there's 10 other manufacturers pumping out crap nobody needs but you need MORE choices?

I want a 2011 type with a 1911-x style slide that accepts M17 mags.

The fuse is pretty cool. Will have to compare with the P320.
May actually like the fuse more.

When did they release this?
They look sharp.

I don’t think most people are interested in much of anything Sig has coming down the road.
