I have been out of law enforcement for 8 years but just joined the local county as a reserve. I am pulling out my USP40 from the safe and my duty gear from storage. I am considering adding a Jet Funnel to the pistol, I turned in my LEO mags when I left, and wondered if there are any LEO's that use this for their duty weapon? I would also like some opinions on night sights. My USP40 is date code KF V3.
