Soundguy, Dillon pistol dies can be quickly disassembled to clean out lube and debris without having to reset them. Maybe not much of an advantage for PC or jacketed bullets but I use lube so I prefer them. I bought mine when they were $20 IIRC more than regular dies and I was sold after my first set so all my pistol dies are Dillons. I only load 9mm, .38, .40 and a bit of .45 ACP so not a huge investment for the ease of use for a lifetime.
The quality of ammunition is not the selling feature of Dillon presses. It is their reliability and production rate.
I do not get anal about pistol ammunition. Clean primer pockets or case length are not concerns. I have never trimmed a pistol case. Productivity trumps "quality" with pistol ammunition. If the ammunition chambers, ejects and delivers decent groups it has enough "quality". KISS
BTW, look at the link below. The Army Marksmanship Unit cannot recommend equipment but a picture if worth a thousand words. I own or have owned every press pictured. My "anal" rifle ammunition comes off a Co-Ax...the red thing at the front of the first bench,
