Thanks for al the answers, last time one of my solders lost a feet during this operation
I wanted to pant a horse, but to put a pin in his feet....
Don't think that's a good idea
If is what you need to ease some works why not?
First you have to put the pins in the horse legs (like in small feet and thin legs) very carefully and gently in the right position, the there's not much room for mistakes.
That's why I prefer sharper needles to pins, like scalpels compared to cutters, being sharper they allow more precision and require less strength.
Sometimes to hold steady the horses I use two needles (the thinnest for painless syringes if legs are very thin) , one in the front legs and one in the back, possibly joined together at the bottom (with some tape or else) to hold both them together.
Otherwise just one deeply planted underneath the body or between one pair of legs, at the end a tiny drop of paint will fill and cover the hole without increasing much the need to handle the figure.
The only little limit using just one pin in this way is the needle pole, it may obstacle some brush strokes in some parts (having to move the brush already between four legs..
.).
A little further trick, you can sand or file the pins and needles top to increase their grip in the holes (and/or use a tiny drop of superglue), or to make them sharper and pierce the bods easier.
Finally if the grip is stronger the pins wont need to go much deep, that make things easier.
