[GRT45]

What is the best way to approach this process? Get a G29 extractor?

I write about your options for the extractor in my post linked below. The extractor topic starts in the fifth paragraph of the linked post.

If your stock 45ACP extractor doesn't function satisfactorily in 10mm service, I've had good results with the modification suggested by KKM explained in the post.
