I bought this 9mm Tisas 1911 B9R, brand new about 14 months ago from Classic Firearms for $425 shipped and put it in my safe, never using it:
https://tisasusa.com/tisas-1911-duty-b9r/ I bought Magpul stocks for it about a month after I got it, and then put it back in the box in my safe, still unfired. I've since bought several other Tisas 1911 models, and took this one out to look at it again, thinking about taking it to the range tomorrow. I function tested it and noticed something. It does this every time I do this procedure:
- Cock the hammer back (can thumb it back or rack the slide - doesn't matter).
- Put the safety on.
- Grip the gun and pull the trigger (remember that safety is on).
- Then completely remove my hand from the gun's grip (or continue to hold the grip - doesn't matter) and just flip the safety off... the hammer falls 2/3 of the way to the firing pin. And that's without the grip safety being touched, nor the trigger.
This is repeatable every time. It does it if I press the grip safety as well. None of my other Tisas 1911's do this (or any of my non-Tisas 1911's either). Short video posted below. Note that this does NOT appear to be related to the recall from last week where the hammer follows the slide on a few models for .45 and 10mm. What would cause my particular issue?
