I'm a big fan of the Sico Omega 9K. It's small and it really does the job considering. I have a longer Mystic X and it's not a bad 9mm can at all (I bought it for 9mm use only really). Both can be used without the booster and with a 1/2-28 insert for use on rifles or pistols that don't require the booster.
Sico makes some nice stuff is always one to check out early on. Quality build, materials, workmanship, design and the ability to use other mfg.'s mounts is great.
Elite Iron makes pistol cans, I suspect they work great but I can't tell you much about them other than his large caliber rifle cans are some of the best made.
AAC has/had deplorable CS --that may be better with Remington, they did replace a mount I waited 2 years on with AAC in just a couple weeks right after taking over. Their materials are top notch (as are Sico's) but some of their mounts are trash, however, that's only with the rifle cans as far as I know.
