I use a level III duty holster at work and I have noticed the hood release will only engage when I depress the tab closer to the attachment point vs. the meatier stippled portion closer to the rear of the holster. Is this normal after only 2 years of use? Is it a spring I can replace or is it the wear and tear on the plastic parts? I don't want to go to release my hood and have it stick, that could be the last thing that I do.
