The T&E guns seem to hold up really well to high round counts - though not all of them are the same as what's being produced in the first batch. The tolerances have been loosened, I'm going to use that phrase despite Dave not liking that language, to increase reliability when dirty and not lubed.Except the part where you can’t shoot it because the trigger broke and trying to fix it voids the warranty. Hopefully they make plenty of triggers or make them high enough quality for this not to be a problem
The side benefit of this is I'd love to see this kind of high quality design make its way in the following years to more large manufacturers of polymer striker fired guns.
