Back in April, I posted a gushing analysis of a 5" SDS "U.S. Army" 1911.

Functionally, the only imperfection out of the box was that it stopped on the link slightly - and I neglected to add before the thread was locked that after 100 rounds the link stretched a tad and made for essentially perfect barrel fit. No stopping on the link, and the locking lugs still cleared the slide. The grand old 1911 is not the cheapest firearm to produce well, as plenty of inexpensive 1911's attest. So getting one that's perfect (individual taste re: features aside) for less than $400 out the door amazed me.

Well, since then I picked up a Commander model for myself, in the 9x19mm that the 4.25"-barrel beast was originally designed for. Colt buffs will call it a Combat Commander, due to the steel frame.

I won't rehash everything from the previous SDS teardown I posted - let's focus on the differences.

Please keep in mind that this post, as the one prior, reviews a sample of one.

Model: 1911A1 TC 9
UPC: 723551440544

We still have well-executed park-colored Cerakote, and the trigger is just as crisp and beautiful, miraculously breaking at exactly the same weight of 4lb 0.4oz.

Unlike the "Army" model, this "Tank Commander" came with only one set of grips - Turkish walnut double diamonds. They are (were) not as figured as what arrived with the full-size pistol. Some Watco Danish oil finish would take the dry look away and dress them up nicely. However, they do not feature in these photos - during initial detail strip, my vicious attach dog decided that the starboard stock was a chew toy.

Unlike the 5" .45, the 4.25" 9mm has a Clark/Para-style ramped barrel. This one doesn't stop on the link at all; instead, out of the box, the locking lugs over-engage the slide a little. I expect them to round over with live fire, rather than peening, due to how slight the issue is. Still disappointing.

Machine chatter was more than on the previous sample, but had zero negative impact to function.

The ramp provides impressive head support while causing no feed issues over the 300 rounds fired at this writing.

Ejector is appropriately extended for 9mm Parabellum. Here it is next to the Tisas .45 ACP government model's ejector:

And here it is with my decades-old Colt 9mm Government:

Further differences between this and the Tisas 5" .45 reviewed prior...
- Steel 9mm firing pin instead of titanium .45 pin.
- Colt commercial "teardrop" thumb lock instead of the tabbed USGI version.
- Commander ring hammer instead of the bloodthirsty spur.
- Taller, serrated sights. They are still installed via staking (front) and a USGI cut (rear).

A white dot would be a nice addition to the front sight, but it's easy enough to stake on a new one if you want the upgrade.

Aside from the overactive locking lugs, the only noticeable defect is that too much frame material was removed for the thumb lock. The firearm passes all safety checks, but I find it maddening that, when disengaging, the thumb lock overtravels slightly before rebounding into place in the "off" position with an audible, tactile click.

I've seen this exact defect on a brand new $4.5k 1911, so as much as it bothers me here... Well, for $400, I can more readily forgive it.

Note: The Commander model reviewed rolled off the production line in 2022, U.S. Army version in 2023.
 
Ahhhh, not even 8am and I have learned something new!
I did not know the commander was originally designed for 9mm.
Thanks for the great review.
You guys are going to force me to buy one of these when they go on sale for labor day.
 
I think Tisas would have done better with the 9mm's if they had gone with the original barrel design that didnt have a ramped barrel. I have two GM's in 9mm and they range between a bit finicky to annoying as far as function goes.

I also think that theres a good chance the extractors on the Tisas 1911's may likely need some attention as well if you have feeding issues. All three of mine have benefited from some tweaking to outright replacement in that respect.

I also have a Tank Commander in .45, and its been more reliable than the 9mm versions, but its very much like a standard GI/Series 70 type 1911 in regards to how well it deals with a mix of ammo. Ball is pretty reliable, but SWC's can be hit or miss.

If you plan on buying one for any kind of serious use, I would skip the 9mm at this point, and I would also have a reliability package, including a T&P, done on any of them, just like any other 1911.

Proper extractor tuning is skipped on a lot of 1911's out of the box, and the non-.45's even moreso I think.

The smaller breachface of a 9mm/.38 (or a 10mm/.40) means that the internal extractor gets un-tuned during the installation, as the extractor channel is bending it the wrong way as part of the installation process. The SDS in this post is one of the best-fit that I've tested out of the box in at least a decade.

Where a lot of alt-caliber 1911's ship with little to no extractor tension, sounds like Tisas over-tensioned your three if the extractors caused or contributed to feeding issues.

Nice pistol! We're so lucky that functional 1911's are so inexpensive right now. :)
Amen. :)

There was basically no tension on the first Tisas (Service model) I got, which was used but looked basically new, and judging by the finish wear on the rails and elsewhere, I dont think it was shot much. At first, I assumed that the previous owner might have been dropping rounds in the chamber and dropping the slide on them when loading, but who knows? The nose of the extractor looked a little beat up and had some finish wear and the hook was a bit rounded.

Both of my 9mm Tisas's would not pass the "round under the extractor" test when I got them. The 45 didnt either, but seems to be working OK.

I have a Weigand 1911 extractor tool, and adjusted the factory extractor on the Service a couple of times and finally gave up on it and replaced it with a Wilson "Bullet Proof", which seems to be holding up and working OK. I adjusted the extractor on the Government as well after the first time out, and so far, function there seems better and it seems to be holding OK too.

The 9mm's are definitely the more finicky and problematical, and I attribute most of that to the ramped barrels and mags, and the extractors seem to be a part of that too.
