You can check all your ammo to make sure its dimensions are within spec, use a quality brand (or reload) that is consistent and clean, check the brass and crimp, and make sure the bullet profile and OAL are OK for your ramp and throat. If your gun is clean and oiled, with appropriate spring rates for the power factor, polished ramp, adjusted extractor, good throat, good mags, etc., and if there are no "operator mistakes", then you should have more than 1000 rounds between malfunctions. I would say one in 2000 max (... hopefully much better).
Your reliability is quite good already, maybe you can try FMJ RN 230gr. ammo (preferably with the not so blunt bullet) or play with your spring rate (what is the power factor of this 185gr. load. It is going to take some time and ammo to find a better load or recheck all details.
