If you read the owners manual you would have realized that you should break the gun down to clean and lube it before shooting it for the first time. At that point you would have noticed you didn't have the tool. There is only one tool for a pro model Kimber (a bent paperclip) what wrong tool did they send you twice? I would appreciate it if you could post a picture of this tool. Did you clean the gun again after firing the first 100 - 150 rounds of 230 gr FMJ ball ammo as instructed in the break in procedure and continue doing that every 100 - 150 rounds until you completed the break in? You say Kimber told you to clean the gun, I think that speaks volumes. I would venture to guess that you originally received a good gun but it sounds like you neglected to read and follow the instructions in the owners manual.
You are correct that I should have cleaned the gun before shooting it for the first time. The tool that Kimber sent me (twice) was a black plastic or fiberglass bushing wrench about 4.75" long with a Kimber logo embossed on it, and that looks like it would fit a conventional 1911. Do you know what I am referring to, or do you still want to see a picture? The third time was a charm for Kimber, and they sent me the correct tool. It looks like a bent paper clip, but seems to be made of a lot harder and stronger metal than a paper clip.
I took a chance by firing it for the first time without cleaning it because I didn't have the proper takedown tool, so shame on me. I gambled and lost. That was two years ago, however, and a lot has changed since then. The gun is clean. The gun has been repaired by Kimber. The gun has a new Wolff recoil spring. The gun now uses Wilson Combat magazines.
I have successfully cleaned the gun several times since that initial event, and I have successfully replaced the recoil spring, even though I apparently inserted the takedown tool into the wrong side of the hole, and I also took a chip out of my ceiling drywall while trying to replaced the spring.
Umm ... you might be partially correct, but not completely so. After Kimber returned the gun, and after they eventually sent me the correct takedown tool (from Montana, not New York), I cleaned the gun before ever firing it again, and before I ever took it to a local smith. Originally, only 11 rounds were attempted to be fired before the gun was returned to Kimber, and before it was thoroughly cleaned. That range visit was on March 15, 2012. The gun was not fired again (by me) until September 14 of that same year, almost two months later. Kimber claimed to have test fired it successfully with no stoppages. When next I fired the gun, the FTF rate had decreased to 1% - 3% for Ball ammunition, but remained very high for 185 gr. JHP ammo from 4 different manufacturers: Remington, Winchester, Hornady and Federal. The Hornady ammo had a 100% FTF rate. Winchester was 15% and 20%. Remington was 10% and Federal was 25%.
That's when I learned about the issue with the recoil spring, and I ordered a new one from Wolff. After installing the new spring, the FTF rates declined sharply. I am now seeing FTF rates of 1% to 4% for all brands, except for
Federal SWCs, which will not feed at all. In the last two weeks, I fired 200 rounds of PMC 230 gr. FMJ ammo with a 2% FTF rate in two trips to the range. I currently have 300 rounds of Remington UMC 230 gr. Ball ammo on order, and I will track its performance as soon as I receive it and can get back to the range.
815 rounds (that I know of) have been fired from this gun. It should be broken in by now, I imagine. I believe that a 2% FTF rate is too high for this firearm, especially considering its price. In fact, 2% is too high a failure rate for any weapon intended to be used for self defense.
