My dept. went to the 39 and many of us also carried it also as a off duty weapon. One thing I did not like was when the magazine was out, the weapon would not fire. Here is why: one of our motor officers pursued a robbery suspect and caught up to him in a parking lot. He bailed off his motor, and took a tumble (wet lot and he just tripped) and confronted the guy with his drawn 39
The suspect made a furtive move, and the officer thought he was going for a gun and tried to shoot the suspect. When the officer went a_ _ over tea kettle, somehow his magazine released and fell by the motor. Fortunately the perp did not have a gun and the officer inserted a mag from his duty belt and took him into custody. This caused us a lot of concern and we all began to make sure our mags were seeded at all times. We also had a couple of AD's in the locker room when a officers dropped their 39's. Ya I know, but we're human Right?
All in all, the 39 shot well and some of us tried the 59 later on. It was just too wide for my smaller hands. Then the Sig P220's came, and I can't say enough good things about that auto. Sweet !!!
