Does anyone know of a file? $20 for each X Grip adapter is really steep. My son in law can easily print some for me with a file.

I have a P229 in .40, and want to use the P226 flush 13 rd .40 S&W magazines in my P229 with that thin adapter. Those 14 rd magazines with the various +2 thick and ugly base plates are too big hanging out on the bottom.

If you come up w/ anything, I would also be interested.
