The tactical thumb safety is very simple, I find it helps to use a very small diameter punch to hold the plunger and spring assembly in place when installing the safety. Once you figure it out, its a breeze.
I use a tiny screwdriver that fits the magazine catch lock to hold the plunger in. That's not the hard part. I just don't want to screw up the hand fitting. One file I bought from Brownells takes off a lot of material even though it's so fine it looks like it's not doing anything. The only time I used it I wrecked a Contender rear sight by widening the notch too much. Before I did that it was so narrow I couldn't get a proper sight picture so I had to widen the notch or narrow the front sight. BTW, sights made for a 14" barrel don't work so well on a 9" barrel because the notch is a lot narrower than the blade. I have another sight and I'm going to try it again but I keep putting it off. I think I'll be okay fixing that, and hand fitting the 1911 safety, if I just file a few strokes at a time.
