I could live with one misfire per flat, or so, with the CompOnes. But, when it's 25-30% of the time......... that won't cut it. I've got two flats on hand right now, and I feel very confident I can find a couple of my hammer guns that they will work in. I'm not bashing them. I really want to be able to use them. If all else fails, the Perazzi will chew them up and spit them out with no problem. The problem can be solved in every case by increasing the firing pin protrusion, but when a gun will shoot every other brand with 100% reliability, even reloads, it's not prudent to go messing with it.
I've got a set of Remington 1889 barrels being refinished now. They previously just got back from being lightly honed by Orlen, and are sound for use. When they get back home they are going to be tried with the CompOnes. Got a feeling that gun is going to work with them.
