I have a two-part question relating to strap buttons.
I've just received a new Kentucky KM-500 A-style mandolin. The wooden tailpiece button is held in only by friction. I find it frustrating as it does occasionally pull out with a strap attached.
Is this ability to remove the pin a mistake or should I glue it in? I do see that if the pin were glued in, any future removal of the tailpiece would be a pain, but still…

The 2nd question refers to installing a strap button on the treble side of heel stock. Are there smaller buttons available or do ones often found for guitars OK?

Thanks

#1: Loose Strap Button - Tailpiece:  Violin end pins are installed without glue. Usually when one loosens, it is a sign that the moisture level in the wood is reducing, as in wintertime. A humidifier in your case or instrument is one solution. Taking a sliver of paper, inserting it into the hole and re-inserting the strap button is often the answer. I did this on a 1967 Gibson Flying V re-issue (1979) electric guitar with excellent results. It stayed fixed for 6+ years. Lastly, you might wet the strap button with water (not soak it, just wet) and re-insert it. It will add the missing humidity and cause the wood to swell just enough to hold the pin or peg. 

#2: Inserting a new strap button on neck heel:  Strap buttons used on guitars are all one size for the most part. Also, they would have to be in order to hold the strap itself as all strap button 'holes' are the same size (unless enlarged from age and use). It is always a wise idea to 'pre-drill'  the hole on a neck heel as forcing a screw into the smaller piece of extremely hard maple could cause it to split. I typically make a pilot hole the size of the screw shaft, allowing only the teeth of the strap button screw to bite into the neck heel wood. 

Hope this helps.

Thanks much. Especially re: tail button. Something told me it didn't want to be glued.
