An aluminum P365?

Yeah, I wouldn’t mind having one but not at that price.
 
Some years back, when metal frames were a "go-to" option for some gun gamers, the companies providing the frames found that metal frames didn't always work the way polymer frames did...

What that meant was that the polymer design allowed a bit of flexibility in part specs -- and many of the after-market parts that worked wonderfully in the polymer frames suddenly didn't work well in the metal frames. They found that many of the after-market providers didn't really adhere to factory specs all that well, but with the polymer guns it didn't seem to matter. (A component ordered from one supplier, reordered a week later, when measured, was often subtly different.

This quirk of polymer vs metal eventually led to virtually all of the metal frame firms closing up shop -- but when things worked well, people LOVED the metal frames.

I would expect this could be an issue with the metal frames for the 365 -- probably OK as long as you used Glock-made parts, but likely to be troublesome if you use after-market parts (trigger kits, etc.)

Not sure Glock adheres to the same high specs as Sig for the P365. ;)
 
I suspect that GLOCK adheres to its own specs - and the parts made this week will be the same for the parts made next week. It could be that some parts have a "fudge" factor built in so that they work well regardless.

But, after-market vendors apparently adhere to a variety of different specs. (As one of the metal frame-makers noted on their web site, the same part ordered from a single vendor, several weeks apart, had different dimensions when received.)
 
Sorry but I’m completely lost. Why the mention of Glock OEM parts for use in a Sig Sauer P365?

I remember an old TV ad that Parts is Parts.

Like everyone else, not sure what the problem is that this is the solution. Would love to know the weight difference. Does it weigh more or less than the polymer and how much?

You are lost, but it's a complex issue.

The mention of Glock OEM parts was to make note of the possible differences between OEM parts and after-market parts.

The firms that made metal frames for Glocks encountered a problem with after-market parts when installed in the new metal-framed Glocks: some parts providers were NOT consistent in their production of parts, and the specs varied. These variances apparently didn't matter when installed in polymer-framed Glocks, but often would NOT run in metal-framed versions. (The same part ordered from a given supplier could have different specs, if ordered again, several weeks later.)

I mentioned it BECAUSE there's a chance that the same sort of issue may arise with after-market parts for a SIG running an after-market metal frame... Particularly when the after-market parts are used to do something the OEM part doesn't do -- like shorten the reset or trigger pull. (When the part is no longer made to match OEM dimensions/specifications, what is correct?) And if there's later subtle differences with a later production run, who is to say the original was right and the later versions aren't -- if they work in the polymer-framed guns, but not the metal-framed versions?)

I've often thought an aluminum-framed Glock would be an interesting experiment, but after reading about the problems with Glock metal frames, I knew that there may be more problems than I wanted to deal with to get one that really worked as it should.

Most of the after-market parts and enhancements were NOT developed with metal frames in mind, and I suspect that there was little incentive for those suppliers to make changes for a very small potential customer base.
