I have carried the P-32 using the clip for years. It's right behind the belt buckle and is absolutely impossible to see.
I used blue locktite and it has lasted nearly a year. I carry the P-32 everykwhere, all the time, all day, wake to sleep. In the house, working in the yard, tilling, driving, etc. it's there, and the clip works great for me.
It's all a matter of personal preference.
