When I was forced to transition to Glock .40 the department wouldn't allow us to purchase our 4506-1 , we had been able to buy the 4506 when they upgraded to -1. 10
years later I found it at a gun show for $300. Still had my badge engraved on the slide. Took all of 3 minutes to complete the sale. Went to another table picked up a spring kit and new night sights for $85.00 carried it as a CCW piece until April. It's now a night table spare. I've gone to an FNP .45 since I have been working personal protection I want as much ammo as possible 15 rounds of .45. Locally Agencies are going back to 9mm. I tried the ammo that they are carrying. FBI may love it but had problems getting it through a windshield. We've had 1 officer involved with the ammo & it did not penetrate well 4 shots center mass guy goes on trial next year.
