I've lost count of how many rounds I've put through mine, but it's easily over 1500 with 1 failure to return to battery. I had the old striker pin, which did not fail, but I replaced it after about 1100 rounds. I'm not happy having to spend $99 on the new pin, but it's become my primary carry gun and I didn't want to risk it failing at the wrong time. It's been reliable and accurate. I pocket carry it along with a couple of magazines. It's amazing that a gun this small with two magazines gives me 37 rounds of 9mm on hand. I understand that the odds of me needing the gun are small, and the odds of needing 37 rounds are immeasurably small, especially since I live about a low risk a life style as possible, but it's so easy to carry there's no reason not to.
In regards to the OP's question, I don't know that the love affair with it is slowing down as much as we're seeing a predictable pattern with a hot gun. They come out from time to time, and there'll always be people willing to pay a premium for them and others willing to sell them at inflated prices. That's the free market. There are X number of buyers for this or any other gun, and eventually the supply catches up with the demand.
