Has anyone here tweaked their feed lips on their semi auto pistol magazines for reliability sakes? If so was it successful? Thank be interesting to know.
 
The short answer is yes and yes , but the long term reliability is always questionable and in most cases new magazines should be used to replace those that fail to feed properly.

Assuming one knows what they are trying to adjust , magazine feed lips as you refer to, can be tweaked to position the shell in a slightly different approach. Don't forget the follower and spring tension also make a difference. Where new magazines can be readily had, it generaly is a better choice because in many cases the temper of the metal has played a roll in the magazine losing its proper lip angles.
 
My High Standard .22LR pistol's magazines have been adjusted several times over the past thirty years. The have been dropped, worn and deburred, or readjusted for different pistols.
Quality magazines can be reformed many times.
 
Don't forget that some feed problems can be accounted for by an accidental reversal of the spring, such that instead of bearing mainly on the front of the follower it bears on the rear.

Or vice-versa.

This can save a lot of fussin' n' cussin'.

They used to make steel blocks which you could insert in the disassembled 1911 magazine so you could re-adjust the feed lips by judicious hammer-taps. I don't know if such are still available --for milspec mags or any other mags, for that matter.
 
Only as a last resort. Almost always successful with 1911 mags, never succeeded with Pro Mags, and needed for about a half my Para P14 mags :(. Try a new spring and follower first. Most effective when I also have a perfectly working mag of the same brand to make comparrison measurements to see where to tweak the bad one.
