I don't own any of KT's rifles but I do own 3 of their pistols and will buy the new single stack 9 they just announced as soon as it becomes available. That being said I've always found KT's guns to have a high incidence of parts failures. Like the above posters firing pin. Yes, KT is a great company to deal with and they'll replace any broken parts for free in a hearbeat. And all guns break parts, but KT seems to have a high incident of it. If this is a range gun it's no big deal, have KT send you a new part and replace it. But if this is a self defense or SHTF gun, you might want to consider going with a gun made by a company known for using high quality parts. I sure wish KT would solve the cheap parts issue, I really like their designs and the company and would be willing to pay an extra 10% or more to get a more durable gun. I have high hopes that this is something that they will work out in the near future. I think they've already taken steps in the right direction, but IMHO they need to go further.
