I've tested the Hi Power now with several different loads, and the following have fed and functioned 100% of the time. I'm glad that what are arguably the best performers are the most reliable.
127-grain Ranger +P+
125-grain Cor Bon +P
124-grain WCC NATO FMJ (+P)
124-grain Federal Hydra Shok
I got a case (10 boxes) of the Ranger today, and after shooting the first magazine full, all I could say was WOW! I have no chronograph, so I have only my very unscientific subjective observations, but based on Mr. Camp's testing, I'd guess that this one is probably about equal to the Remington .357 Magnum 125-grain soft HP fired from my 2 1/2" Model 66.
I don't have any 115-grain +P ammo on hand to test, but it seems that the modifications I've made to this gun are going to require either heavy bullets, heavy loads, or both in order to function well. Since installing the 18.5 lb recoil spring, I don't think I've gotten through a full magazine of 115-grain standard pressure ammo without some kind of malfunction. For instance, standard velocity (1,150 fps) 115 S&B FMJ ammo functions 100% in an unmodified MKIII, in the MKII, and in my FEG.
Anyway, here's the full list of modifications for those who weren't paying attention the first time
*Removed the magazine disconnect
*Removed the Millet target sights and replaced with Trijicon night sights
*Added an 18.5 lb recoil spring
*Added a C&S extended thumb safety
Added a C&S ring style hammer
*Added a Shock-Tec recoil buffer
The final step will be to replace the sear, but to be honest, my budget isn't in any shape to do this right now. I've read that the harder C&S hammer will ruin the original sear, but I simply can't afford to do anything else right now, so it'll have to wait.
I probably would have spent less money getting someone else to do the work for me, but look at all the fun I had getting to this point!
Thanks to everyone for all the suggestions and information. Ya'll probably saved me a lot of heartache in the long run. Here's something of the progression in pictures:
While I'm at it, does anyone have any information on my magazine carrier? I don't really remember where I got it, but it's a handy little devil. There isn't any information on it anywhere, but it's made of what seems to be spring steel and is finished with some sort of black lacquer.
Oh yeah, and it fits Hi Power magazines.
