Sounds like the trigger sucks & it’s not particularly accurate.
For $1,600, a Geiselle Trigger should be SOP, and accuracy is a serious mfgr problem. I’d pass if I was looking at one. My hardware, as I’m sure yours is, is well-broken-in and finely-tuned. No need to get into a crapshooter.
Did you get one of those $99 bumpfires?
