You do realize there's an extensive tested ammo list right? Everyone acts like these guns, out for like five years now, are still shrouded in clouds of mystery...
Finding ammo that won't pull apart is no different than finding a hollow point that feeds reliably (though quite possibly easier)
Arne's problem is simply that the concealed carry market is really crowded, and the gun market at large is cooling off. Hopefully his 9mm and 45 designs are keeping him fully employed (I suspect they are still selling well).
The main critique nay-sayers have is the pull feed scheme. Strangely, this is the
exact system used successfully in countless heavy machine guns, from today spanning the entire last century. I'm so sure it's inherently flawed. No, it's simply that handgun ammunition is made to extremely low standards far too often, so much that shooters don't even realize they are running bullets that are loosely crimped (or not crimped) and can be either pulled from,
or pushed into the case with the mere force of recoil. Machine gun ammo is properly crimped so this does not happen; quality handgun ammo is properly crimped so this does not happen. End of story.
Strangely, nay-sayers hardly, if ever, comment on the other "questionable" traits. I'm no function/testing expert, let alone on Boberg's but the off-set recoil spring (of 1/4" or so diameter), supposed "self lubricating parts" that still retain faint texture of machining, lack of magazine follower, and use of sliding aluminum parts internally all give me more pause than the feeding tongs. Apart from the mag non-follower that occasionally pops out the mag lips and cases issues, there have been few reports of problems with these other items.
Mainly, it's just people trying to use badly-made ammo in the guns, which are uniquely intolerant of it. At least they won't set the bullet back and grenade in your hand like push-feed designs, though.
