At 25 yards had a very nice small fist sized group, so pistol precision increased as expected with the more stable platform. Had to be mindful of the offset of the RDS optic vs. the G19 bbl or would affect location of grouping at 25 yards (did not see that accuracy vs. precision issue at closer distances). Roni appears to grip pistol primarily at front of frame, so that malfunctions seemed to increase vs. classic two handed semiauto pistol grip, especially with longer (33 round Glock factory mags) - so advantage of larger capacity mags in question. Shot factory new 124 grain NATO and 124 grain +P JHP, no felt recoil to speak of. Front of pistol slide came out of Roni quite dirty, luckily its a Glock so will not require any cleaning
