Detection and Prevention of misfires
You got some good advice. Find a competent gunsmith and establish a good working realtionship with him. He can examine your firearm and let you know if it is up to snuff, and if it isn't, usually he can make it so (tip of the hat to Captain Picard.) Buy good ammunition, and clean and maintain your weapon on a regular basis. If necessary, take your cleaning kit to the gunsmith and have him teach you to properly clean your weapon. If you do these things, you will reduce the chance of a misfire by almost 100%. If you do have a misfire, keep the weapon pointed downrange for thirty seconds, in case the round is cooking off. After that time period, carefully clear the weapon and dispose of the offending round. Do not be overly paranoid about misfires. In all the years I have shot, either for qualification or in competition, I have only had one misfire. I the same period of time I have had four problems with ammo. One was a squib load which made me disassemble my Dan Wesson Arms revolver and use a dowel rod to drive the wadcutter out of the barrel. Our department at one time issued Silvertip hollowpoints, and I discovered a light round. It turned out that there was no lead in the aluminum shell. The armorer said if I had fired it, it would have been the fastest .45 ACP in history, but that it probably would not severely injure anyone. Remember, the loudest noise in the world is a click when you expect a bang, and the second loudest is a bang when you expect a click. Best of luck, I think you will enjoy the semiauto pistol.
