How many "test rounds" are enough?

[Hazcat]

From what you described I would think its enough. You did not say whether you used any lubricant before or during your shoot. Run it in a condition you would carry in . I usually only shoot a box or two, if I have no problems I'm satisfied.

My plus 1 on this as well.  You gave it a good work out.  It sounds to me like it runs well.  If'n I wuz you I would be happy and carry with NO problem.

For me it's around 200 rounds. That is enough to "wear in" any rough spots that might cause a FTF or FTE. It also will allow any issues to pop up and be corrected. A while back I bought a "Baby" Desert Eagle in .45 ACP. The gun right off the bat had feeding issues that were attributed to a rough feed ramp. I took the gun apart and polished the feed ramp to a near Diamond polish condition, completely cleaned and lubed it.

I returned to the range the next day and ran 4 boxes, (200 rounds), through it without a hitch. I have no problem trusting that gun in it's present condition, cleaned and lubed.  Bill T.

Welcome to DRTV. I ran 140 rounds through my Ruger LCP when I first purchased it. Regular Remington Ball Ammo, Corbon and Hornady Critical Defense. All fired well but was more accurate with the Remington ball and Hornady.

No issues with FTE, FTF, etc.

It totally depends on the gun. I wouldn't carry a 1911 that didn't have at least 500rds through it but I'd almost feel comfortable to buy a Glock and load it and carry it. I've carried both for over 20 years so I know what my personal experience with each is abd what to expect from them. I felt my LCP was ready for carry around 120rds because of the mix of ammo I ran through it, including mixed magazines of various hollow points, fmj and reloads. I've never heard of one having an issue unless it was right out of the gate. If you've put 50rds through an LCP and didn't experience any issues I feel your GTG. I don't think there's a rule, just go with your gut. If you feel it will work for you then have at it. I think your better served doing some self staged malfunction drills than just blowing through ammo to reach someone's magic number of carry certification.
