Just wondering. I have had mine 2-months.
Didn't like the trigger is came with so changed to the Wilson Combat TTU -- but experienced constant double-fires which is no-good.
So just changed it out to a Geissle SSA-e and hoping for the best.

Also since I am in California they have the stupid maglock in place, and have had lot of issues getting magazine inserted and released. I use regular magpul magazines.

I had a V1 and then upgraded it to a V3. Both were awesome and the V3 is better than the V1 with the adjustable gas block for suppressed/unsuppressed. I run a Geissele SD-C in mine and no issues at all.

Have about 600-800 rounds now through my new DD5V3. No issues thus far, even when running suppressed.

Stick with a Geissele trigger, but since you are in the PRK, who knows what mods they have to do to the rifle to keep Sacramento happy. No issues with my Geissele SSA trigger in the DD5V3.

Double fires might be due to a missing firing pin spring.  Make sure yours is installed on the firing pin, without it slam fires could occur.
