I've got 3, two for me one for wife
had to send one in for a fail to feed,
They seem to be picky about bullet profile.
They all shot round nose fine, but I also had some blunt nose (flat on the tip)
& even some hollow pts that wouldn't feed consistently they did a ramp job on it & it works fine
& I shoot
Hornady "Critical Defense" rounds, which are more conical in profile
& they all feed these w/ no problem IMO, and its a really good round
(They sell "em as "Zombie" rds for about $5.00 more & have a snot green tip)
I've had no problems with them since & I carry it on me on a daily basis
See if he'll let you put a box of rounds through it.
I did put an extended floor-plate on mine 'cause it truly improves handling
here's a few images
Pic #1 is a sign at my local indoor range, the bldg is 1/2 gun range 1/2w/ church!
