If you have the Crimson Trace laser on the front of the PM9, please discuss the good, bad, and ugly for concealed carry. At personal defense distances, does a semi-auto benefit?

I have the CT grips on my snubby revolver because I may need to defend myself with the revolver held at waist level, due to injury or struggle. But a semi-auto would be limp-wristed in those positions and won't function anyway, right? In other words, doesn't a semi-auto need to be held firmly enough to point shoot at self defense distances (0 to 10 feet or so)?

So, does a laser earn its way (weight-wise) onto a pocket semi-auto pistol for personal defense?

Thanks for your help!
