From my experience with the Auto-Ordnance side and their customer service I would wholeheartedly not recommend them.
To be fair they were completely in their right not to honor the one year warranty to the original purchaser, upfront I told them it was originally purchased over that time frame and that I was second owner.
But, it was a well known failure of the bolt, fracturing of the extractor groove allowing it to jam in the receiver, this problem was discussed in many different forums including a Kahr specific forum. This I found out while researching the problem. My original call to customer service got me a "no warranty, goodbye" and hang up. I messaged them on FB, got a half-hearted reply.
If they had offered me a 50/50 split, a parts coverage and I pay the labor or the opposite, something, anything, I would have come away satisfied. All I got was that I could send it in on my expense both ways, they would inspect it and advise me of the cost to repair it.
Until that first day I took it to the range and it failed it had zero rounds put through it, the failure was less than fifty rounds. When the extractor pops out and the metal of the bolt is flaking and in addition one of the firing pin grooves developed a crack when removing the roll pin I would say metal embrittlement due to incorrect heat treating. And again, in all fairness, the replacement bolt has functioned fine, no signs of embrittlement or cracking in the firing pin retainer pinholes to date.
I purchased the parts to repair it from them, over 300 dollars this was in 2014. If this had been a cheap gun that's one thing, but that Tommy gun
retailed at the time for over 1200 dollars with the accessories.
I won't name the forum but they have a sub group that discusses the semi Thompsons. And that failure is still a common issue.
Sorry to be long winded but I felt I should fully explain this.
