How to get info on a model that was only produced for a short period of time? 1997 .45SUPER not ported or Lone slide.

I've had this gun for a while and I'm just curious on the history, and production numbers. The only good info I've ever found was using the web archives. 1997 was the only time I saw this gun on the site archive.

1997 .45SUPER PI45CUS. Years ago I was told yes it says custom on the part number but it didn't go through the custom shop. That was the best I got from Springfield customer service.

Just curious if anyone on here had access to any better info. This has none of the porting and is not a longside.

Don't know if this is the same or not or helps
 
Thanks,

I was looking for more of the actual model info from Springfield. I’m curious how many they actually produced of this model. I think I’ve only seen 1 other. The rest of the .45 super stuff is the v16 that I’ve seen.

Just posting again to see if anyone had some connections at Springfield for this one. Just curious on if there was anything else special about it. Production numbers would be nice for that year.
 
I’ve seen plenty of the long slide models.

I search every so often and have maybe seen 1 in the wild as the same as mine from the website clip. And the one from Springfield website 1997 shows it being standard length and ported but mine case matches the part number PI45CUS.

Just curious the history.
 
Any idea what makes it different from a regular 1911 in .45 acp? I’ve shot plenty of super from a 1911 with a 28# recoil spring and an extra power main spring and a flat bottom firing pin stop.

I was just wondering if it was possible to shoot that in a standard 1911 with more powerful springs.
 
Since the .45SUPER was such a short run from Springfield I don’t know what beyond a stiffer recoil spring they did. Part of the reason I’ve tried over the years unsuccessfully getting any better info from Springfield.

You can shoot .45SUPER in a regular .45 with just charging he recoil spring. However the question is can that barrel handle the increased pressures the .45Super makes.

The 45SUPER brass also different internally. The webbing by the primer is thicker.
