Ditto what others said on riding the slide stop with your thumb, you likely will impeded the slide from locking back on an empty magazine.
With my hand size and grip I prefer using the lower profile slide stops on my P01's and SP01's (sku# 0650008002). the low profile slide stops have a shorter overall length, just something to consider if when you ride the safety with an aggressive and high grip and your right thumb is resting on or near the slide stop. Other people adopt a grip where the tip of their thumb/distal phalanx points upwards to towards the top of the slide when riding the safety which also allows you to avoid riding the slide stop (as opposed to bending the tip of the thumb/distal phalanx down when riding the safety, the method I prefer). Hope this helps!
