...while I do miss the job (it was truly an adventure of a career), I do not miss certain aspects of it like some arsehats with whom I worked (mostly supervisors). Don't get me wrong - some of the supervisors were great especially the Primary Firearms Instructors (Range Masters) and my friend DP. I readily admit that I also miss many of my fellow agents.
Other than my coworkers, the things I miss most besides travel to temporary assignments were my collateral duties as a firearms instructor for handgun, rifle & shotgun and then what came a bit later on - certification & collateral duties as an MP5 instructor. If I ever loved a gun (besides my 870) I loved the HK MP5 that was issued to me. While I still have my Remington 870 12 gauge (in fact I have two), I of course had to give up that MP5.
Damn, shooting it was fun - especially with the free ammo I got from the job for practice. There was a lot of free ammo to spare; so, you can safely bet, I shot that MP5 frequently. If I had to rate it among all the long guns I have ever owned or been issued - it truly rates as the most fun long gun probably tied with the 870 but it might edge out the 870 only in as much as it never kicked enough to hurt my shoulder!
All the best,
