I have been reloading for a while I have never crimped pistol rounds, I am going to start reloading 45acp rounds should I get the 3pc or 4pc set. I have a lee progressive press and I have been doing 9mm. and I have noticed the 4pc set is out of stock everywhere and the 3 pc is in stock everywhere. What do you think?

I seat and crimp in separate steps, so I use the 4 die set.  Whatever you decide to use, you still need to apply a light taper crimp to remove the flare plus maybe a thou or two more.

I load 5 different pistol rounds on a Lee progressive and seat and crimp in the same step for all of them. It can be done if you take the time to set up your dies right.

I crimp everything, light/medium for auto rnds, medium for revolver. Crimping helps reduce bullet set back / pull out issues and holds the bullet just a bit longer for complete powder ignition.

Get a case gauge to check every rnd in.

If you are careful with die set up you can use the 3 dies. I would get the 3 die set since it's available now, if you feel the need for the 4th you can still get it later.

How have you been reloading 9mm and NOT crimping? What do you remove the mouth flair with?

I seat and crimp in one operation but I load on a single stage press. If you can't find a 4 die set you have 2 options. 1) Seat and crimp in one op. 2) Buy the Lee FCD (factory crimp die) separate. If you are going to be loading cast bullets though I would not use the FCD.

You could probably buy a extra seat/crimp die and set it up to crimp only too.

Same here. Get the 4 die set.
