[xskylitox]

This guy talks about how to convert a gun designed for .45ACP to .45 Super:

use the super ammo in the gun for self defense. if you are involved in a self defense shooting the gun is going to be taken away anyways for most likely several years where it will sit in a box in an evidence room until the case goes to trial or is settled. then in some states you have to submit paperwork in order to get your gun back which takes time. some departments actually engrave the case number into the slide of the weapon. so by the time you get your gun back, if you do get it back, and are not sitting in jail, its all dusty and dirty. you're probably gonna want a new gun anyways so if it does break thats just another excuse to get a new one.

I shoot .45 Super thru my Tactical on a regular basis. I added a heavier spring set because the slide felt like it it was slamming against the stop. With the heavier spring set this has stopped. Vortex compensator helped alot with recoil and muzzle flash.

I've shot a couple boxes of Buffalo Bore 185gr. & 230gr. I've been been slowly working reloads to the point where last batch I noticed some bulging of the cases. Using a 260gr. Nosler Partition Gold. I backed powder charge off a bit in my last reloading session, but have not been to range to test yet.

Next trip to the range, I'll take my chrony and report back.

I'm at office now, so I don't have my notes with me as to spring weight or my load data. PM me if you want me to email you info.

If you can reload .45ACP, you can reload .45 Super. Same die & bullet. Just a stronger case and a little more powder.

I've shot a few hundred rounds of 45 super through my USP and Tactical with no problems. I took a hog with one a few years ago as well. You should be fine.

None of the above applies In FL

Be sure to let us know how long your gun lasted...

i have a 45 expert would that spring work in my gun and where would i pick one up and for how much ??

I know that HK recommends limited use of the .45 Super in the USC (carbine). I can't find my .45 Tactical manual right now, but I would imagine if the carbine should see limited use it might be wise to avoid it in the pistols. It would IMHO cause increased wear and tear on the pistol and isn't really needed since they are +P rated in any case. I don't even feed my .45s a steady diet of +P ammo. I'm not out to 'break my USP', or any other gun I own for that matter. ;)

I was thining about buying some underwood .45 super just to have on hand for woods carry (not regular carry)
