My recommendation is to get a Lee Bulge Buster, and not use the Factory Crimp Die for crimping, reason why is as the bullet passes thru the carbide sizing ring the bullet is resized, that is bad for accuracy, the FCD will make pistol ammo feed 100% reliable but at the expense of accuracy, that not a trade off I'm willing to except. I run all my 40 thru the Lee BB, then FL size, Bell, and seat bullets with Hornady dies, I crimp with a Redding taper crimp die to .421, my current load is 3.0 grains of Clays, and 180 grainers, my Glock 35 needed a 15lb recoil spring to function 100%, this load is accurate and soft, with a Power Factor of 130k.
