Sig P320 SXG Reserve
I have grown to really like the metal and steel P320 variants. This week, I picked up a Reserve model to round out my collection. For those that don’t know, the Reserve is the steel frame variant with the comp from the Legion model. They are finished is a very nice high polished DLC.

I honestly don’t know if I’ll shoot this one or not, as I already shoot the X-Five SXG and AXG Legion (love both).

Some pics, but they don’t do it justice. It’s not an easy gun to photograph.

















Here is is with my other P320’s, as well as my P226 X-Five Reserve

Do those raised gripping ridges work well for grasping and cycling the slide? It appears their edges are somewhat rounded from the polishing.

Random little detail I didn't notice before, but does anyone know why they just went with a single slot on the 1913 rail on the SXG?

^^^That's what I was thinking too, but I really don't know.

1KPerDay, bac's second-to-last picture shows the original SXG (left), the SXG Reserve (center), and the AXG Legion (right). The original SXG only has a single slot.

I think it’s all about weight for the X-Five SXG. They were probably trying to get it to 50oz and they damn near did. It’s 49.4oz with an empty magazine.

That's a solid looking firearm!

XFive SXG
Hi, That is the gun that got me interested in the P320. I was set on a purchase around the time you posted this. After a bit of reading through other sites on the differences between P320 guns, I purchased the P320 XFive SXG instead. Mine is a late 2025 build... oddly having no SIG insignia on the back door of the slider.

I would not touch the reserve. Make a display case to admire. It will not shoot better than the XFive SXG due to not being refined for Competition.

As for mods on the SXG, they are simple and cost effective. I run a stock trigger with a return spacer under the front of the trigger. It maje a near zero to the wall set point shown in the picture. That was a freebie self made mod.

Ordered a few 1911 variable rate recoil springs. A 2.5 lbs trigger pull kit and a gas pedal. Nothing else is required to make the SXG perform.

On big issue is the finish... it is a coating not a real bead blasted finish. After a weekend of manual break in to loosen it up, my skin has worn smooth spots that shows up the stainless like a mirror. The I had to pry the release lever to get it to move. The hard plastic rubbed the area around the release lever... it too rubbed the finish. Other than cosmetics being cheap, the XSG is is solid.

The refinement between the X-Five and the Reserve is the same. They are built to the same standards. The X-Five is about 4ox heavier, due to the longer slide and rail. That being said, the comp on the Reserve will make up the weight and then some. At 45oz+, the Reserve is still a heavy pistol.

But you’re right, the Legion and X-Five are my shooters. In fact, the Legion shoots softly even with the aluminum frame.
