Had high hopes - Elftmann Tactical Elf Pro SE Trigger

I will start with the good. The trigger is a great upgrade to the factory. It is smooth, has a clean break and short reset. Now the bad! The 1st set of them sent out had the hammers breaking between 1 and 100 rounds. Mine lasted about 100 rounds and I have friends who have broken at least 5 in as few as 1 round. Great customer service in the sense that they replaced them all. However, the new springs they sent were too long and did not fit in the lower receiver. I was told to use the original springs. Now the trigger pull is down to 2.2lbs and we are getting primer light strikes. Also, the hammer screws are continually backing out, even with loctite blue applied after degreasing the threads. Waiting to here back from them with a solution. Appears as if the customer is beta testing the product.
