I'm new to reloading and am trying to figure out about whether case trimming is needed for handgun loads. I have a .40SW and a .357 magnum and can't find a real answer. I was assuming that case trimming is needed on any case that measures too long, but I did not see anything in the instructional videos I have been watching that shows trimming a handgun case, only rifle cases. I want to be sure I'm doing things right, so if I need to buy a case trimmer I want to go ahead and get one. Thanks!

Yes, you should check them. Pistols do not produce the pressures of rifles but the brass is thinner and should still be checked. Ctgs like 9mm are fairly high pressure. Consistent case length will also help with accuracy and if you crimp.

Many thanks!

You won't be working the brass nearly as hard as FL sizing a bottlenecked rifle case, but like the man says, it's worth checking. I like the Lee trimmers for handgun cases; you can check and trim in one operation.
