The pistol was carried in a 7TS ALS holster, mid ride.
ETA:
I tried flushing the pistol with my bottle of water while on the course(slide lock, dump water into the back of the gun). No improvement.
After the race I pulled the slide and flushed the frame with a garden hose. This improved things but the trigger still had a sluggish reset and wouldn't return fully forw6under it's own power.
Ultimately I had to detail strip the gun and wipe down the trigger bar, connector, locking block, and slide release with a towel. I then re-lubed and it's back to 100%
Pretty bad experience overall. I've run tons of these races with Gen3, 4, and 5 19s with only a minus connector and never had an issue. I've also had the guns in much worse conditions.
It's obvious the GPT is extremely sensitive to dirt and grit. I'll be removing mine and going back to a standard style trigger.
