If you like the SAR5 except for the lack of guard, having somebody add a guard to something like the SAR5 is very feasible.
Outside of just bolsters, there are generally two type of attachable guards: those with a single hole that go over a hidden tang (not what you want) and those with a slot cut from above that is mounted from beneath and pinned. This could be added to the SAR5.
There are many guards to chose from. Some are pre-shaped. Others are just blocks of various metals (nickel-silver, aluminum, brass, stainless, etc.) that need shaping.
Remove the scales. They will need to be ground back behind the guard to fit.
A 2nd hole could be drilled above the Talon Hole (which is flat in the Ricasso, to pin a guard.
To much else to explain, but basically just re-build the SAR5 with a guard.
.... For that matter, many knives can be modified or altered many different ways.
Res-C handles could be modified to hidden tang scales, etc.
