I bough the Bondarms Bullpup 9 as my everyday carry (EDC), & I've now been carrying it every day since September 22nd 2021; that's 1yr & 9mos!
I carry it in a "Sticky Holster" for pocket carry in my pants, & to facilitate this method of carry I replaced the rosewood grips with the thinner & lighter black-plastic grips. The thinner plastic grips make the grip much thinner, & the overall package lighter, which are both really good things when carrying all day long.
I've shot probably ~13 different types of ammo thru it, & indeed there are some "non-crimped" ammo types which will often separate the bullet from the casing, which spills the gunpowder into the magazine. It just means you have to test your ammo at the range, so you avoid using that ammo. I've never had it happen with any Hollow Point defensive rounds, only FMJ "range ammo."
Overall, other than that bullet separation of cheap range ammo, I've never had a failure to feed or extract, which is what we want from our EDC!
