For myself, neither the Hogue Handall or the Pachmayr grip sleeves work well (I've tried both). The finger groove "bumps" crowd my knuckles.....and as I have slightly enlarged knuckles due to RA, this leads to pain. This is why I began using the inner tube grip sleeve method. However, I've since stopped using it, as my current pistols both fit my hand very well.
So, you see, one size does NOT fit all in matters like this....so to speak. To each his own, I say.
