The Gun of the Week is my latest personal acquisition, a Kimber Ultra Aegis II in .38 Super. Those of you who are serious gun students will know that there is no such thing. Kimber doesn't make a .38 Super in the Officer's size (3″ barrel, short butt). Also there is not one listed in the California approved gun list. But I wanted one anyway. So I had it built.
I bought a perfectly legal Kimber in 9mm. The 9mm and 38 Super are similar enough in size around the base of the case that the firing pin and ejector are OK and the extractor is pretty close. The magazine well is built for a .45 ACP, so the .38 Super magazines work just fine. It was then a matter of having the barrel sleeved and rechambered for .38 Super. The 9mm bore is .355 and theoretically the .38 Super bore is .356, but in fact most modern .38 Supers have a .355 bore, so there shouldn't be an issue there.
It did need to have some fitting done and as the barrel positioning was a bit off from the factory. I also had the grooves removed from the trigger face as they were so sharp I found them uncomfortable.
The weapon is checkered on the alloy frame front strap and back strap. It has very good low-profile three-dot sights, which I may very likely replace with Hi-Viz or Meprolight sights in the near future. They are dovetail mounted already so that is easy enough to do by yourself if you have a sight pusher, which I do.
I am hoping that this will turn out to be comfortable enough for me that I can shift from a summer gun and a winter gun to this as a year-around gun. After I put a few hundred rounds through it, I will know.
