I carry the 1911 officers model in winter.
Tucks away real nice.
Last week, I found a YT video about Kimber 3” & 4” 1911s, and the Kimber guy was saying that both the recoil spring needs to be replaced from 17lbs to 22lbs, to eliminate FTFs and jamming. He also recommended to replace the guide rod to 100% fix the problem. Also choosing specific ammo to run in the gun.
Might be in these vids:
