Asymetrical barrel lugs: what to do

[Cump]

How concerning do these lugs look on this unfired Zastava m57 (new manufacture)?

I'm not surprised or unhappy because I know these pistols can be rough, and this one's trigger is nice, and there aren't any other visible issues.

Also, there is no noticeable play when pressing down on the hood in battery, and lock-up seems okay when manually cycling. I'm waiting for an ammo order to do the most common-sense test ...

Biggest questions: could the roughness and asymmetry lead to continued erosion of the lugs or atypical wear? And should I go ahead and get a new barrel (which are low stock)?

That 3rd lug contact surface - the top part looks quite shallow. Like those lugs were cut with the barrel off center in the lathe. This will affect lugs contact with the slide and not in a good way. 2nd & 3rd barrel lugs should have .053" height, while the 1st lug should be .073". A qualified gunsmith might be able to cut those lugs deeper and reset the barrel - it's hard to tell from a picture.

Thanks for the measurements. Prob going to get another barrel, but see how this one shoots too.

Ignore them, if the pistol shoots OK. They aren't visible anyway, unless the gun is stripped, so they are not a visible cosmetic flaw.
