Yes, P99's are being used and eagerly accepted in Law Enforcement. I'm happy to say that my local city Police Dept now carries and issues the P99 in 40 S&W. They tested many guns,didn't want Glocks and are very happy with them. They would have been happy with anything ,considering they traded in very old heavy stainless S&W's ,but they really do love the P99. Its lightweight, accurate and very adaptable to different hands and accessories etc. Whats not to like.
