.45 super

[papa]

Has anyone here shot any .45 super ? If so does anyone know if any of the 1911 Springfields , with modifications , would handle the .45 super.

The only standard 45 acp guns that would take a regular diet are the HK USP and HK45 (maybe the FNX 45 but not sure) as far as 1911’s unless specifically rated tread with caution.

I know the Federal 230 HST Plus P dan be hard on the so that tells me I would t run them regularly

But everyone can do whatever they feel comfortable with!

A friend of mine had/has one.

But it maybe better to go the 460 Rowland route since .45 Super conversion info seems to be unobtainable & you can shoot .45 Super through a Rowland conversion.

There's alot of old info out there on the net so that's why I'd go with a 460 kit.

Besides a "fully-supported barrel" its recommended to use a #32 recoil spring in a stel full-sized 1911, HS firing pin spring changes & mag spring changes.

This page openes but nothing seems to work (at least on my end) in the pages links. Ace Custom doesn't seem to be in business anymore.

Cartridge of the Week: The .45 Super

The .45 Super The .45 Super is a powerful handgun cartridge that is externally/dimensionally identical to 45 ACP or 45 ACP +P. Developed in 1988 by Dean Grennell, a well-known writer in the firearms field. It has a thicker case wall and is loaded to higher pressures, which offers an average 300...

I’ve shot it in HK USP’s with no modifications, but they are designed for it.

Usually, you’ll need a heavier recoil spring in a 1911. Sometimes you’ll need heavier mag springs as well for reliable feeding.

Thanks for the reply everyone. I knew heavier springs would be needed and figured a barrel swap would be a good idea. Not looking for a steady diet of it. Just looking for a little extra oomph once in a while at the range.

The .460 might be a better option.

I hadn't thought about mag springs but makes sense because of faster slide action. Thanks.

460rowland max pressure @ 40k
45super @ 28K
45acp @ 21k
45acp +p @23k

big difference between the 3 (excluding the +p). i know a person that has a 1911 460r setup, but not sure about spring pressure. it is suggested to use a brake with the 1911 and glock conversions. glock doesn't require as much spring pressure. going super in a 1911 w/o brake you might need to add 4-6# to spring weight. i've been wanting to do a glock/m/p 45acp to 45super conversion and not batter the frames. when tuned correctly it doesn't take a tole on the frames.

I’m definitely behind the power curve on all of these non-standard calibers. I need to do some research

While 460 Rowland has higher pressure levels you can shoot 45 Super in a 460 Rowland set-up
