My old A-Zooms are starting to look pretty bruised up after 8 years worth of dry fire through a number of different handguns. Lots of rim wear, the primer cushions have permanent indentations, and due to the stepped chambers in my P30s, the case mouth is starting to chip away too. Are there any other snap caps that are considered "the best" or are these still it?
So far the other options I've seen look to be the ST Action Pros, which don't have any sort of cushion in the primer pocket, the Tiptons, which have a neat spring-loaded primer but I've had bad experiences with (had some for my shotgun and the plastic cracked in short order), and a handful of options on Amazon I've never heard of.
About the only complaints I've ever heard about the A-Zooms is the whole "aluminum shavings in the gun" thing but I'm not 100% if that's fuddlore or not. Obviously the anodized surface wears away over time, but I've never heard of a verifiable instance in which it's caused a critical component failure (though I haven't looked for instances of that very hard).
