"Extended" magazines are killers, generally they don't work.
Use Wilson Rogers Stainless 7 rounders - I feel good with a 7 round magazine in a 1911. I any situation you find yourself in an extended magazine is useless anyway and it will get you killed. A handgun is usually a DEFENSIVE weapon - a jam is nightmarish!

The spring shouldn't cause any damage of this type, because the follower is between the spring and the cartridge. It would have to be either the extention or the magazine throat joints that would cause cuts or scrapes on the cartridge. Anything that could cut the plastic hull that deep would be enough to jam the feed cycle and should be very obvious.

Did your friend use the anti-tilt follower that comes packaged with the Choate extension, or the factory, cup-style follower? The anti-tilt unit reduces the round count to 7 - 2 3/4" or 3" shells, but works flawlessly; for me, at least.
Get yourself a Glock, and lose that nickel plated sissy pistol.
