I'll play the devil's advocate here. The .357M was devised in the middle thirties for Hoover's G-men to shoot through car doors at fleeing felons. The .38 S&W Special has some decent offerings today - mostly +P-rated - that are great 'fight stoppers'. I keep the Remington R38S12 158gr LHPSWC, the old 'FBI load', in my 2" 10 and 642, althought there are purpose built rounds, such as Speer's 135gr Gold Dot JHP, that are also effective. Doug Wesson showed the utility of the .357M at it's ntroduction by hunting most of the N. American big game with it.
The .44 Magnum - derived from the .44 Special, which came from the first widely used centerfire handgun metallic cartridge, the .44 Russian - was actually developed as a hunting round (Sorry, Harry Callahan!). I love shooting mild .44M's, .44 Specials, and .44 Russians - from my .44M's. I had my time with a heavy recoiler - a SRH in .454/.45... I don't get the recoil thrill these days - and don't miss it!
Okay - my suggestion. You have a bottom-feeder in .45 ACP.... how about a revolver that uses them? The S&W 625 is a SS revolver chambered for both moonclipped .45 ACP's and clip-less .45 Auto Rims. It is available new now as a Jerry Miculek special, the 625JM, in 4" and the standard version in 5" - at about $40 less than the feature-laden JM version - check an '07 S&W catalog - or their site. The 625JM is available locally for ~$680-$700. I've had mine since they came out - and a standard 4"-er before that.
The beauty of the .45 ACP in a revolver is multi-faceted - no 'action' to work, as in your 1911, so no min/max power level (... within SAAMI spec's!) to worry about. Mild poof loads to .45 Colt plus level loads are possible. The moonclips make reloading FAST. Unlike your bottom-feeder, a revolver won't rudely cast those empties upon the pavement - they stay 'NICE'! Besides being a reloader's friend, they are also available much more widely than even .357M and .44M - and at lower prices. The recoil isn't bad - what more could you want? A real big bore that is frugal and won't destroy your wrist! Good luck.

The black tool is for stripping the .45 ACP's from the metallic moonclip. The thick rimmed cartridge is a .45 Auto Rim - which fits the HKS #25 Speedloader. S&W has made .45 ACP revolvers since 1917.
