A true but humorous story:
In the late 1980 I went to a small rural county Sheriffs Department as a Patrol Deputy. I was issued a S&W Model 19, a Colt Model 1911A1, A Remington Model 870 (14" barrel) and a Marlin Model 336 .30/30.
Going to the firing range for qualifications:
On firing--
1.S&W Model 19,the rear sight adjustment screw broke off and the elevation went all the way up.
2. Colt Model 1911A1, went full auto
3. Remington Model 870 12 gauge- stock split at the pistol grip
4. Marlin Model 336- rear sight fell off

Returning to the office, I returned the issue "Firearms" and received permission to use my personal firearms.
