Sent it off finally. Left the house on Monday. Arrived at SA on Wednesday. Fixed and shipped out on Thursday. Will arrive back home on Monday. That's quick turn around.

I've been holding off also, for the same reason. Also, I'd be curious if the trigger pull has changed on yours. I've read some reports to the effect that the update increases trigger pull.

Still as of yet have not sent mine in.have about 1500 rnds through it.No issues and my trigger is pretty good.

Got it back today. One week to the day. No apparent difference in the trigger.

That's good to hear. Thanks for the report.

I had two pre-recall guns and sent one in early and held the other one back. The upgraded gun has a trigger pull that is a half pound heavier than the one that was not upgraded. The upgraded gun has less creep after the takeup and before the letoff, which makes it more predictable in slow fire. I prefer it with the upgrade. I sent the second one in after the initial rush.
