How reliable is reliable enough for a carry handgun? This is likely to be a personal question and oneís opinion may be influenced by the line of work they are in and likelihood that the gun will be needed at all. But, Iíd love to get your inputs on what realistic failure rates might be expected for a gun you think is reliable enough to carry as your only weapon.
It seems like one would want a gun that can fire at least 10,000 rounds without a single failure. Is that practical? I have a Sig P239 that I bought used that I have put more than 1,000 rounds through without a failure.
On the other hand, I have a new M&P Shield 9mm that is in for warranty repair already after more than 20 FTFs in the first 200 rounds. Over that same period it also had 3 FTE (all 115gr FMJ from 2 different companies). Some of these failures were in the last 20 rounds so I expect it should be past the initial break-in period failures. I donít want to say anything bad about the Shield because I love the gun, the size and ergonomics are excellent for me. I am hopeful that S&W will diagnose and fix both problems soon. But, how many flawless rounds would you put through the repaired gun once its returned to be sure it is reliable enough for a defensive carry weapon?
