Your results with small pistol primers & mag primers are similar to mine; not much difference. I have not used small pistol mg primers in years.
I too have never trimmed pistol brass.
Some people do not like the trimpro because the back part wobbles. The trimpro was designed so that when the pilot enters the case mouth, the pilot squares the case perpendicular. There are those that prefer the collet type.
My first trimmer was a Forster, It is over 40 years old and works great. Like I mentioned before, I use the motorized trim pro for big jobs.
