Hello,

18DAI:
1.The city guns had Novak style night sights, with stardard S&W roll marks.[ My personal 4506 and a couple of my Smith revolvers have the 2.SIS logo engraved on them].
3.Don't recall the serial number prefix.
4.SIS did not have a particular holster. I believe I used Ted Blocker and Aker holsters.
5. Mag. pouches were either single or double, detectives choice. I usually wore one, but that would be adjusted based on the case we were working. I normanlly wore one .45 and spare mag or mags, had something else on my ankle or pocket, another .45 between the seat and shoulder weapons in the back seat.
6. Chief Beck seems like a good man. I've seen him wearing a S&W .45 uniform. He may have started a school for officers that haven't been trained on the DA auto. Sounds like something the department would do--good idea--bet I haven't heard.
