The first thing is a 200 round break-in period. Check your mags, and use the most dependable ammo. You need to buy a box and shoot half, and save half. Now figure you have a single shot in your hands, and make the first shot count. If your Rohrbaugh jams, then throw it at the perp and pull your back-up. In the end it is always better to avoid the situation to begin with. The dark parking lot, the ATM, the midnight gas station, the Road Rage.
I decided to buy a S&W 642 ..... wow, what dependability ...... never had to shoot it ... finally I did, and it went 'bang, bang, click'. It had a bad firing pin - light primer strikes.
The lesson here is all guns need to have 200 rounds through them - and even revolvers like certain ammo
