Of the 3, one was gone, one busted, and one in place. Only got about 1000 rounds through it. Luckily, they are cheap. On that note, any recommendations on what and where to get them?

Also, any chance this impacted my recent (lousy) shooting trip last week?

Hard to imagine it matters in any way, but I happen to like the JPE ones, but they are not traditional. But in any case for the traditional ones everyone, everywhere has them. I doubt it was related in any way that I could conceive.
