    A1 Safety

    Bought this to swap out the ambi one on my duty model. Dropping in fine and have had no issues with it thus far. Part is black cerakoted btw, since it doesn’t really mention that on here figured I would.

    Ambi replacement

    Bought this, which I prefer over an ambi safety, for a 1911 B9 Commander. I anticipated having to do some file work to get it to work correctly. But, it dropped in and passed all function tests with no fitting required. Tisas has some pretty good QC or I just got lucky. YMMV

    I own a Tisas B45 Duty 5 full size pistol with ambi safety. I wanted to get rid of the ambi safety because I carry this gun daily and many times I would look down and the safety had re-set itself to a fire position while cocked and locked. The ambi safety was catching on my clothing and disengaging. So, I bought this right hand thumb safety. I removed the ambi safety and installed this with no issues. It works perfectly and stays in a safe mode while carrying cocked and locked. Perfect fit factory part!
