Whats the best trimmer for handgun cartridges?

Any suggestions? I'm thinking of getting a Lyman Universal Trimmer.
 
You don't need to trim handgun cartridges. They will almost always wear out before they would expand in length to the point you would ever need to trim them.
 
Yep, the Lee Trimmer with a cordless drill here, too. I buy the cutter with the big wooden ball on it, for an easier grip.
Lee makes a lock stud with a 1/4 inch stud to chuck into a drill. This is a great combo.
The Lee Chamfer Tool, after trimming, may be held in the off-hand for a quick-spin chamfering.
I disagree that pistol cases never need trimming. They DO stretch, particularly the .357 and .44 Magnums, in my experience. To get a uniform crimp, particularly a roll crimp into a bullet's cannelure or crimping groove, a consistent case length is mandatory.
I check all my pistol cases for length, before loading. It's a good habit to get into, especially when using cases new from the factory. I've encounted newly manufactured .38 Special and .44-40 brass that exceeded the maximum length. God knows how it left the plant that way, but it did.
 
I've been reloading the same .44mag cases (Remington) for several yars and they have not grown at all. In fact, in the 15 or so years that I have been reloading I have never seen a handgun cartridge grow.

Of course, if you are getting different results from your particualr gun, then you may need to trim them.
 
I have experienced variations in lenght of my revolver cases up to a 1/100 " and the case mouths has been out of square 5/1000" with once fired brass. Before I started trimming my revolver brass, I could not get a consistant roll crimp. Now all is as it should be. :)
 
I was always under the impression that it was most important to trim handgun cartridges because of the uniformity required when crimping.
 
I only trim cases that head space off the rim, for a consistant roll crimp. I have had no need to trim cartridge cases that head space off the case mouth, my dies for semi-auto use a taper crimp.
