How’s this:

Tisas are made in Turkey.

Hard to see on the screen, but is it as porous as it's coming across in the picture?

Something weird going on with the back. Looks like there are two divots stamped into it and it appears that it broke along the lines of the divots. I don't know what purpose those stampings/divots serve. I think they don't need to be there.

Also, looking at the front of the guide, it seems that the surface is uneven or maybe the thickness varies a lot, comparing the wear marks.

[Jim Watson]

Maybe Br will show us the frame to examine for uneven contact next Wednesday.

I was curious about those myself as I have 2 Tisas, a 10mm and a 45. I stripped both down to inspect them and neither one of mine have those dimples.

Buy American!

Bought a Tisas near GI Clone. Mag catch broke in less than 50 rounds through the gun. It's MIM, of course, and I knew that when I purchased the gun. Like most bad MIM, the part broke early. The company sent me a replacement mag catch. I no longer own that particular gun but do still own the "Duty" model.

My Duty model double fires about every 7th round. There is a current “recall” for hammers following the slide but my serial number isn’t included on the list. Tisas customer service hasn’t impressed me. Will take it to my own smith so he can make it safe for using.

Sounds like a Chi-Com MIM part going janky. You want U.S.-made tool steel only.

[JohnKSa]

Tisas, and presumably their parts, are made in Turkey. Turkish steel may or may not be especially good quality. I can't find any good information on the topic.

Tool steel is a bad choice for most gun parts--probably for any of them, truth be told.

The U.S. is not the only country that can make good quality steel.

[Aguila Blanca]

And Turkey isn't the only country that makes MIM parts for firearms that occasionally break.

Kimber uses a lot of MIM in their 1911s -- so much that they have earned the nickname "Mimber." A few years ago there was a run of Kimber 1911s that had the hammers break. MIM part. Bad batch? Probably ... there are hundreds of thousands of 1911s out there with MIM hammers, yet breakage is rare.

How can you tell if a part is MIM? Do newer Colts, Rugers and S&Ws have MIM parts? I wonder how many MIM parts are in a commercial air liner or in the brakes or steering components (or other critical systems) of a car?

[Jim Watson]

A tube through a flat plate seems not a good choice for MIM. It looks like what contractors have been fabricating for many years.

I have three Tisas 1911s, each with about 400 rounds through them.
For whatever reason a while back, I changed out all the recoil spring guides with Wilson combat units.
They are much more stout than the Tisas provided ones.
I am very impressed with these pistols in and I am enjoying them.

I had a hot post planned in response to this comment, but have withheld most of it so as to not violate forum rules and get too political, however:

-I will spend my money when and on whatever I please & my safe is full of
"American" firearms

-using this logic, all Glock, SIG, Berretta, Krieghoff, Perazzi, Browning (FN),etc
shooters have got it wrong too

-ammo brands Federal, Speer, Remington and Fioccchi are now owned by a
Czech company, you better only shoot Winchester

-your Ford or Chevy is full of Made in Mexico parts better not drive one

-Walmart is full of stuff Made in China, no shopping there

New Wilson recoil spring guide rod, (short one piece variety) and a new Wilson 16llb spring installed. The new Wilson spring is notably longer than the OEM spring with near 1500 rds on it, like 1-1/8" longer. I suspect the OEM spring is shot out and a major contributor to the part breakage.

The Wilson "bullet proof" guide rod appears to be one solid milled piece and should more correctly be labled "bomb proof". Really quality item with a bit of heft to it as well.

Ran 50 rounds of mixed 230 gr hardball and reload "softball" through the Tisas today, ran like a champ, Wilson mags.

[Aguila Blanca]

To my surprise, I discovered that the original Ordnance Department design for the guide rod was a one-piece fabrication -- but hollow. I always thought the guide rod and head were a press fit through the flange.

[bamaranger]

The Tisas OEM guide rod is hollow and interestingly, open at both ends. There is a pronounced radius at the forward end to facilitate the spring collapsing over the guide rod. I have looked at the thing carefully, even with a glass, and cannot say as to whether it is one piece or two.

I suspect however, since it is hollow and open on both ends, Tisas took a piece of tubing, cut appropriate radius on both ends, then swaged or riveted the flange in place. Note: speculation only. It may well be one piece, I just can't determine. But if it is indeed two pieces, that would seem a faster way of making the part. Stamping out the flange (might explain the "divots"), cutting the tubing, and attaching the two. Possibly one of the difference in a $300 pistol as opposed to one costing 3X more.

[Aguila Blanca]

The mil-spec guide rod is open at both ends.

I think literally every part in the M1911 was a machined forging.
Specs were changed on some parts over time- cast slide stops were allowed in the '80s!
Advertising says every part in a new Tisas 1911 is machined, no cast or MIM, but I don't know when that change was made.

Biggest change was between 2022 an 2023. They changed as they used up parts on hand to there is no single date. But by 2023 dated guns almost everything was forged.

Forging is how the receivers of M1 Garands were made. Old School durability.

As the M1 pros say, “cast don’t last.”
