You really won't find a exact match, all the .45s' are single stack so the grips thinner and longer front-to-rear. The 4583 is more of a Commander size, full sized grip. The compacts beside the PC Shorty 45 would be the 457, 4516, 4553(DAO) and 4513 both in TSW versions also.
Then there is the PC 45 Recon if you can take the ported 4 1/4" barrel. This comes in black and stainless versions. If you really want the cat's meow, you can get the .45 C.Q.B. This is a 4" barrel and comes in all black, tutone, and all stainless. It is a highly sought after PC Pistol and is very versatile.
