I owned (2) Kimber Target pistols - Kimber Dedicated 1911 5" 22LR Target Pistol - the reliability was terrible - shooting high velocity round nose ammo (recommended by Kimber) I would have 2 to 3 fail to fire per magazine. Kimber reworked the match grade barrel and bushing, etc. and it worked fine for about 200 to 300 rounds then it all started again. Approximately 70% reliability is not good enough.
The other was a stainless 1911 5" 9mm Target II pistol that had accuracy and reliability problems. Kimber basically told me that I was just lousy shot and I should practice more, use better ammo, and not to worry because it will get reliable after 500 rounds.
That person annoyed me since they had no idea my level of marksmanship. I told them I shot almost 800 rounds of high quality factory ammo through the pistol and it's still unreliable. They said if I send it to them in Yonkers, NY they'll take a look at it but could be up to 8 to 12 weeks to get it back.
Instead, I took both guns to a local gunsmith and he got them working fairly well. That wasn't a cheap repair but I knew this guy would get them working right.
He bought one from me and sold the other for me. My son, my nephew, and many others swear by Kimbers. I don't.
