They all seem to be problematic, nature of the beast.
I've used them all, some hold up great others don't
I've settled on the Sig's cause I've got three that have lots of rounds on them and have no problems.
One DPP going on a new build
We'll see how it goes, other DPP's have been good overall with 1 going back for service,
It's like reloading to me, if you're going to shoot a lot you have to reload a lot.
If you're going to shoot slide mounted optics you're going to have to replace them occasionally.
FWIW
