I did FEA to simulate putting 100 lbs of force onto the end of one of the prongs for both a BE Meyers and BLACKOUT flash suppressor. Both were simulated using the same settings and type of material.

BLACKOUT:
Lowest factor of safety: 1.33
Max von Mises Stress: 1.65929e+008 N/m^2
Max displacement: 0.147 mm

BE Meyers
Lowest factor of safety: 0.41
Max von Mises Stress:5.39317e+008 N/m^2
Max displacement: 0.528 mm
Conclusion:
BLACKOUT had a factor of safety that was 3.25 times higher.
Stress in BLACKOUT was 3.25 times lower.
BE Meyers prong was displaced 3.59 times further distance
