TISAS recall

[bamaranger]

This was news to me, perhaps to others, so I'm posting same.

TISAS has a recall on certain 1911 model pistols within certain serial# ranges. Note that it does NOT apply to all TISAS 1911's. Rather than trying to list what I have loosely read, check the TISAS website. Four or five models are involved.

Only certain models are effected and given the wide range of models that TISAS sells, not overwhelming. The issues apparently is the hammer following the slide forward upon loading.

Fortunately, my Duty model is not one.

Thanks for the notice. My gun is safe. I really like my Aviator Commander.

Is there a link we can follow on this recall? I don’t see any mention on either the TISAS or SDS Imports sites.

Oops found it. Blue banner farther down the TISAS site. Thanks

Manufacturers of much more expensive pistols have also had safety recalls. Tisas makes decent pistols for a very attractive price. The fact that a few of their pistols may experience hammer follow doesn't change that.

Several posts have been deleted. This thread is a discussion of a safety recall. This is not an appropriate place to engage in brand bashing.

The issues apparently is the hammer following the slide forward upon loading.

It's just my own curious nature, but I'd like to dissect and eyeball one of the offending samples to see just what's causing that. Does the hammer follow upon slide release? Or just when loading and THEN when the slide is released?
Out of spec interrupter? Too long of a trigger band?

It's usually somethin' simple.

They don't say whether it follows to half cock or all the way to the slide.

If it's the former, the sear spring needs more tension on the center leg.

If it's the latter, something is interfering with full sear reset.

There's quick test for the former.

Lock the slide open. Pull the trigger and hold it. Release the slide. If it doesn't follow, it's the sear spring.

Since they didn't mention doubling, slam firing, or burst fire, we can probably skip that part.

No, but they do say not to load the gun before they get to check it out because it could lead to property damage or severe injury, which suggests a bullet getting loose rather than just battering the sear nose with the half-cock notch.

When I was shooting bull's-eye matches forty years ago, it was common practice to keep the trigger pulled when releasing the slide on a 1911. A lot of guys, not knowing what they were doing, would lighten their own triggers and get sear nose angles too steep or fail to put a relief angle on it, over-shorten the hammer hooks, over-lighten the sear leaf on the flat spring, etc. A lot also had the heavy Goldcup trigger, whose inertia, on a light trigger, was great enough to overcome the little sear buffer they'd added to mitigate that issue, and to knock the sear off the hammer hooks when the slide's momentum transferred to the frame as it went into battery.

Or, maybe they're just being extra cautious and exercising a little CYA.

Like you, I remember the practice of holding the trigger during a reload to prevent hammer follow to the half cock. The safety nazis lose their mind over the suggestion today.

What happens is that when the slide jerks the frame forward the trigger stands still and bumps the disconnect and rolls the sear off the shortened hammer hooks. Holding the trigger to the rear before releasing the slide keeps the disconnect out of the way.
