I had mine break a block. I want to say it was at about 5,000 rounds. I was told it was A lack of lube on the block. I do lube the pistol often, but I was shooting in 105+ temps, maybe it wasn't enough?
I now make sure I lube it, before every range session. I also started using 5w-20 Mobil 1 for the lube. I don't worry about it in between stages, it's stays wet throughout a match.
It doesn't take long for the slide to get too hot to touch, during summer in southern Arizona. I've put another 10,000 on it and I haven't seen any issues so far. I do keep a close eye on it. I do like the Honcho, a lot.
