I got a couple of firing pins from Jack First (http://www.jackfirstgun.com/index.php
) for $42.00. Thanks Shooter45!
I checked with High Standard in Houston. They wanted $60.00 for two firing pins plus another $10 to ship them the 300 miles from Houston to San Antonio. I would have done it if they were the only game in town, but it seemed a little ridiculous to me.
I got the grips from Vintage Gun Grips. I didn't even ask High Standard.
