I’ve currently got a P320 full size with a WC full-size grip module on it that I’m looking to put in a Flux Raider chassis.

In doing that I plan on getting a new full size to replace it. I can get a new full size for $465, or a XFull for about $700.

I’m going to reuse the WC grip.

Is there a $235 upgrade between the Full and XFull that I’m missing? It’s just factory flat trigger and X grip frame right? All new 320s are now optic cut.

It seems like that is all there is between the two for the most part- the grip module and trigger. The X-Full can accept the Sig mag well and the grip weight but that doesn't matter if you are using the WC grip module. I like the flat trigger on the P320 but the curved on the P365, so I tend to like the X-Full.

I was able to get an older used P320 X-Full- ( the rear sight is mounted to the optic plate and not a big deal for me), for less than $300 on Gunbroker, just a few months ago and am using it in my Flux Raider. I got it in amazing shape from a gun store out of state, as they were selling them due to all of the "issues" with the model and wanted them gone. Flux does have a blem Raider chassis,when they have them in stock, for about $50-60 less than a non-blem and the blem has the same warranty. I can't find what makes it a blem as it works and does what it should. If you are going to get another P320, I would look at Gunbroker or the like for a used model and save a good chunk of change.
Be the change you want in this world.

The X Models were originally designed as having the X Grip, flat trigger and optics cut.
They started optics cutting everything a year or two ago. So now, it's essentially just the grip and trigger.

Yeah I think I’d rather save the $230, buy a Sig flat trigger with the new gun Sig shop discount coupon, and reuse the WC grip
