I used to think the Kimber Ultra (3" guns) recoil spring replacement schedule was 500 rounds, but the topic came up recently elsewhere, and I had to look it up. Kimber has their Owners Manuals available on line, so I checked.
Kimber recommends replacing the recoil spring every
1,500 rounds in their Ultra models, which surprised me.
See page 68 in the Owners Manual

Yea, they must have made changes somewhere along the line.
I no longer have the manual, but Im positive it was much less than 1500 rounds, and by at least 1K rounds. The fact that I had to keep changing it just trying to get the gun to work was very annoying, and still never gave a good result.
Even at 1500 rounds, thats not very awe inspiring round count, and not much of a window if youre practicing with the gun on a regular basis. If I were carrying one, at the current rate, Id be changing that spring about once a month. And something tells me they are getting a bit more than the $7 Glock charges for one, and its got a 7500 round +/- rating.
Another thing I wonder about when I hear that the 1911's in general are 100% reliable. I carried and shot them (GM's and Commanders) for decades, and compared to things like my SIG's and Glocks, of any barrel length, definitions of whats considered reliable, seems to differ a good bit, at least if youre being honest about it.
I havent carried a 1911, and spent most of my time shooting them like I did about 20 years now, but I still shoot a number of different versions of them on a regular basis, and pretty much every one of them wont make it through the couple of hundred rounds I usually shoot out of them when I am shooting them, without some sort of stoppage. And that's with a couple of guns that have been gone over to alleviate that very sort of thing.
Compared to my other guns, SIG's, Glocks, Berettas, etc, the stoppages arent near as often and they seem less sensitive to ammo and mag issues as well.
I get the feeling sometimes, that things are being graded on a curve here.
