I am so glad you asked before buying it. Don't waste your money, Mine would not reset without adjusting it out to the maximum, and even then half the time I would have to flick it with my finger. I got rid of it. The internals are like the r51, very cheap, the frame holds the trigger bar and spring in place. If you open it up you will not want it anymore once you see how cheaply it's made.
The gun actually shot OK before fiddling with it, they aren't made to be taken down all the way. Nothing fits right. The gun is just cheaply made, not like a glock or kahr, just a hot mess. The trigger wobble drove me crazy, their tech told me it was normal because they were seizing under heavy use, so instead of putting in a spacer, the just left 1/8 of inch of play on it. If it shoots just leave it alone, definitely do not waste more money on it
