I'm kind of particular about reliability of firearms.
By that I mean, if I cannot adequately contribute a mechanical failure of a firearm to some issue related to ammunition, a magazine, or a recoil spring issue - I get a little gunshy (literally).
Example: I grabbed the Kahr CW9 out of the pistol-safe in Texas when I flew in carry-on. I unloaded the gun and brought it up to dryfire and it had a dead trigger. After some time diagnosing I discovered a broken trigger return spring. This gun has been sitting in the safe and/or occasionally carried for the past 4-years, it has less than 2000 rounds through it.
Once this gun is fixed, I will sell it with disclosure, why? Because I never carry a gun that breaks in this manner. I can't do it/won't do it, whatever.
What is your mindset regarding a "broken" gun. Particularly one where there is a failure for no clear reason (like why is a trigger spring broken after <2000 rounds?). Do you fix, keep, and shoot on? Or do you fix and move on?
