On anything other than match grade gun, I like to see around .005-.008" clearance around all the rear of the tang & the non-port side & and a couple more on the port side & see that there is no battering on the barrel face from the slide.

(With a match grade gun you would have started with an oversize tang & would have fitted it a little closer especially on the rear surface)

I also make sure that the underside of the tang is chamfered & polished so as not to impede a round going into the chamber.

With today's better commercial guns, the tang fit is rarely bad enough to be an issue.

Another area that usually needs some attention & can impact the barrel/slide returning to battery, especially on a new gun,is the corners of the locking lugs in the slide & on the barrel.

Assuming that the basic mating of the lugs allow good lockup, I always chamfer the back edges of the lug recess on the slide & the front of the lugs on the barrel.......doing this will allow the barrel to both unlock & return to battery easier.

This is accomplished with a file on the barrel lugs then polishing, & with a scraper on the slide.

The absolute max chamfer is 25% of the lug surface & usually about 15% is plenty sufficient.
