I use a Lee handheld I've had for probably 20 years - works great for the price I paid and it seats them quite consistently and quicker / easier than trying to use the press for it (little rcbs reloader special).  Only part I've replaced was the spring.  Not using press type shell holders is a bit of a pain, but not that bad.  Someday I'll save up enough pennies for a progressive...

Not sure how true it is, but I've also read that putting in a stronger recoil spring instead of square bottom firing pin stops and stronger mainspring can cause the slide to spring forward more forcefully and can put additional stress on the locking lugs and the link / link pins.

Glock 20SF for me.  Highly likely a Gen4 29 will be added when I can save up for it    Is there a name for this 10mm addiction, cuz I'm pretty sure I have it
