Long take-up and over travel. Putting a Johnny glocks vex on it is nice, but as is I'm not a huge fan. Compared to stock it's fine, aftermarket, nah.

The M02 was serviceable, but not bright enough for me. It absolutely was difficult to see outdoors in matches and was replaced. No issues with the RTS2, SRO, or 507comps.

To add another data point. I have the w74 + 14lbs Commander spring and 29N striker spring and this combo seems to run flawlessly on my gun. I tried 13 but it was noticeably sluggish and 14 performed better than 15 for me. The biggest change I've seen is with the springs+followers when shooting mags with +4 baseplates. I have the mbx spring+follower installed and it appears to address my issue of occasional FTF when shooting 147s. I never ran into FTE issues and haven't touched the extractor. Your mileage may vary but the above works for me.
