@BUCK8154 Several years ago I remember seeing an STI that was a double stack 9mm basically Commander  size, 4”/4.25”. 

The websight  is tough for me to navigate on my phone and it’s blocked on my work computer. Is there a double stack Commander size 9mm model today?

Staccato-p

Thanks, much, Buck.  Much appreciated.

This is an interesting thread to watch as I’ll be eventually putting together a commander length slide on a double stack frame from Ck Arms.

Buck, I’ve seen STI 2011 frames on Brownells’ site as special order items. Do you know if these are current production frames or maybe they just haven’t updated their inventory?

If this next build goes well I’d like to try a STI frame with a Caspian slide instead of the rougher Fusion I currently have.

AKFireCop's commentary is spot-on. As is JS7SFGA's thoughts.

Lately, there have been good reports from several sectors on STI's pistols. Enough to believe those saying they are now viable for duty use. I think I have one of the 9mms on order, think. I'm looking forward to getting time in behind it.  

I've got one of The Unit STI .40s from another time. It gets shot once a year. I'm not able to offer an sort of competent opinion off of it though. 

That’s funny, I have one of those as well. Didn’t know what it was when I bought it.  All I was told was that is was a T&E gun from a MIL/FED GOV program. At the time my Agency was all .40 and I wanted a 1911 ish gun for work ammo. It runs well with Lawman and HST 180. 

What's the difference between the Duo and the HOST? Can't seem to find much info on the Duo, besides what was already stated in this thread.

Plus ça change, plus c'est la même chose.

From what I can  gather open source, the original HOST used MOS type plates but allowed the optic to sit lower than most MOS type systems. 

Here is a good review of the original HOST system: 

https://spotterup.com/sti-tactical-h-o-s-t-hands-on/

The DUO or HOST II system is like that found on the SIG M17/18/X series guns.  Basic rear sight is part of the no optics cover plate. Remove it and the basic cut is for direct mount of a DPP pro. No BUIS - it’s intended to use a BUIS mounted to the rear dovetail of the DPP.  I heard there may be an Dawson DPP pro rear BUIS which is supposed to be an improvement over the Leupold factor BUIS, 

Gun also comes with an adaptor plate for RMR footprint optics with a built in BUIS.  The adaptor plate has bosses to support the optic kind of like the C&H aftermarket MOS plates and supposedly has an improved mounting  geometry. 

This video from Jim Dexter gives a good overview of the DUO system. 

 

Its funny, I always thought that STI used a variation of Para-Ordnance style magazines, but all the recent videos I have seen show that STI mags narrow to single stack at the feed lips, and only flare to double stack further down the body. Probably why their reliability is much better than Para-Ordnance, they get to keep standard 1911 feed geometry.
When I am working again, I might have to pick one up.

I owned a Marauder in the 2015ish time frame. I put about 3000 rounds through it using STI mags. I had a couple of failure to feeds which I'm confident were from my high thumb grip slowing the slide. Once I went back to support thumb on frame, the problem went away. I still miss that Marauder. So much I picked up a Hex Tac last month. Now to figure out who is the best option to put a red dot on it.

The HOST used plates for all optics, which created a problem with our first federal contract, The US MArshalS SOG, as they are fielding the Leupold DPP.  The DPP has a taller base than other optics, so when mounted on a plate you cannot have co-witness backup sights unless you have  ridiculously tall sights, then the gun won't fit in any current duty holsters.

The DUO direct mounts a DPP to the slide at slight forward angle as to make it quicker to get on the dot from the draw from the holster.  All other optics use a plate that sits on the dup profile.  While Dave Dawson(Dawson Precision) was creating GEN 2 HOST for us he discovered a way to machine the slide and plates so that when removed, and re-installed, the optic would retain its zero.  Dave then patented the system under the name DUO, which is our current system.

While the DUO was designed to be retrofitted to previous slides with a novak or LPA style cut, we do not have that set up as an option at this time, but possibly next year will be available.

We have never used paras magazines, nor have we ever used one piece doublestack 1911 frames like para.  2011's use a modular frame which gives you three benefits over a double stack 1911 frame:

1. Lighter weight

2. Grip circumference that is only 1/8 - 1/4" larger in diameter than a 1911 single stack grip with standard grip p[anels.

3. 30%-65% reduction in recoil energy transferred into the grip compared to one piece frames...this is why 2011's shoot so soft and flat.

Buck, is there any word on when the Staccato P 5, will be available?

I picked up a used STI 4" Tactical as a warmup for my Chambers Nightfighter as I waited for it to be completed and shipped. The STI was a good representation of what to expect. Having used mostly Glock/Sig/CZ/Walther I didn't quite understand what I was getting into - until I started shooting these 2011s and seeing for myself the advantages.

The first 10 or so minutes of this link Chuck Pressburg (aka Roland aka Basicload) and I discuss that advantages over Glock and similar.

There's no charge for awesomeness or attractiveness.
