I should have laid a better foundation for why I'm asking. Here's the deal... I'm shooting a P18 and my hands aren't quite big enough to get my thumb around to the mag release without creating some serious movement in my grip. So, I'm trying to find a way to add an oversized button. My mag release is not tapped so I would have to replace the entire piece. All that being said, I'm guessing I'll still have to stick with Para parts. Why are they so darn hard to find? Geez.....
