I put 170 rounds through it tonight without a hiccup.  I shot a mixture of 115 gr UMC, 115 gr Wolf, 124 gr NATO ball, and 135 gr +P Critical Duty.  I haven't shot it suppressed since the ATF hasn't let me have my Tirant 9 yet, but I may get to shoot it with a buddy's YHM can this weekend.  I didn't do any real accuracy testing, but it shoots better than I do.  No problems making a 12 oz Pepsi can dance at 25 yards as long as I did my part on the trigger.  So far I'm pretty happy with my purchase.

Looks pretty good.  Will the thread protector stay on fairly well?

I didn't run more than a couple mags through it without tightening it, but it never  came off. It stays tighter than my Storm Lake barrel in my G17.
