STI Open 40

There's probably too many variables to say for sure whether or not a 1.125 OAL will work for your gun. There's a good chance that it will work, but you may have the occassional hiccup. My reliability improves the longer I load for the 2011 with 1.180 being the sweet spot for my particular gun/mag combo using 180 gr Extreme Heavy Plated Bullets. I finally bit the bullet and decided to have two separate .40 loads for my guns (1.135 for my TS and 1.180 for the 2011 w/ tuned STI mags)

They may or may not work depending on the gun. Most STIs like longer loaded ammo especially with the minimalist followers. If you wanna run short ammo, I would use the factory followers first and Dawson followers second. They do not give maximum capacity but are pretty forgiving as far as ammo is concerned. As for the load, I would suggest against the 180 grain and get the lightest bullet you can with the slowest powder you can. The 40 is already at a disadvantage in open as your giving up capacity as well as powder/gas volume with the heavier bullets. With 180s especially with a fast powder your basically shooting a limited gun with a dot more than a compensated open gun.

Any suggestion on a type of powder that will work with. I have on hand these powder; Bullseye, Titegroup, 700x, N320, N340 only. I will try to get the 135 later. Thanks.

about 8-ish grains of N340 with a 135 gr Rainier works just fine. I will have to get back to you on OAL. If you use the 180's, you will pretty much be shooting a loud limited gun.

The sad thing is, I only have a 180 gr bullets. I look up at Midway and they have a 135 Rainier, but not sure if the length of the 135 gr is enough to handle the OAL of 1.18 for the STI.

I was loading to 1.157 with the Rainier. My frame is a Para but I am using STI for Para tubes and grams innards. If you want to spend some money, you can use the Nosler 135 JHPs. Do what you have to do but I have found that 135 is the upper limit if you want any sort of flatness.

Excellent advice ^^^
