Hello all! First post here on this forum. I was looking for a gunsmith who could mill down a hammer trunion so I could fit a heavier hammer spring. Unfortunately I have a fairly new gun on the market and so far I have found no luck in finding an aftermarket hammer spring for the gun. (MKA1919) So I am looking for someone to machine the hammer trunions to .27" from .353" so I could fit a heavy aftermarket hammer spring. p.s. I'm fine with a respectable machine shop as well! thanks! Thanks.
