I have put a lot of rounds through one of these and zero problems to report. I am at nearly 1300 rounds so far and zero malfunctions. Firing pin drag thing is BS, inside of the slide is experiencing normal wear like any other semi I have owned. Sights are awesome, trigger is fantastic. Glock fanboys gonna hate...
It is amazing how a few people with skills enough to put together a video and post some comments on line can alter perception of so many. Don't be fooled, go try one for yourself, you won't be disappointed in the least.
The primer drag issue is real. Sorry.
