What is the test for admitting evidence of prior possession of a handgun similar to a murder weapon?

A trial court's ruling on the admissibility of evidence is reviewed for abuse of discretion. (People v. Hamilton (2009) 45 Cal.4th 863, 930.) " ' "Evidence is substantially more prejudicial than probative (see Evid.Code, 352) if, broadly stated, it poses an intolerable 'risk to the fairness of the proceedings or the reliability of the outcome' [citation]." . . . "The admission of relevant evidence will not offend due process unless the evidence is so prejudicial as to render the defendant's trial fundamentally unfair." ' [Citation.]" (Ibid.) " 'Relevant evidence' means evidence . . . having any tendency in reason to prove or disprove any disputed fact that is of consequence to the determination of the action." (Evid.Code, 210.)

[Citations.]" (People v. Barnwell (2007) 41 Cal.4th 1038, 1056 (Barnwell) [trial court erred in admitting evidence of defendant's prior possession of handgun similar to murder weapon where prosecutor did not claim such weapon was actually used in murders]; see also People v.
