Do modern 1911's feed hollow point ammunition reliably?

Have you found any particular brand to be problematic or perhaps ones that feed more reliably?

Or is this going to be a trail and error thing find the right ammo that feeds reliably? This could get very expensive trying to find the right self defense ammo.

A side question. 45acps are pretty slow. Is there enough velocity there to allow the hollow point to expand?

Thanks for your feedback!
