I shot 500 rnds of the 124gr rn reman in my glock 19 with no issues. Shot a match and in the 6 stage I had 3 rounds that fired but failed to cycle the slide. The gun was obviously a little dirty by then but far cleaner than when I fired the first 500. I have some 147 I haven't tried yet. A buddy I shot the match with had zero issues with the 147 in his 5.25 xdm with several thousand rounds of various grains from freedom.
