Just got back the M! Garand trigger housing group that I sent to Mac, the 'smith you referred me to. The trigger IS lighter- used to have 8# pull, now probably 4.5-5#. Far as I can see he must have cut off half or even one full coil off the trigger spring. Cost me $50, a fair price, I would say.
He said he builds match rifles in .308 and 30-06, restocked, glassed (bedding), match sights, etc., and is willing to pick up my rifle if I can't ship it to him. However, I am not planning to shoot match- just seeing dem holes in the black, scattered though they may be, is enough to warm the cockles of my heart.

If any reader would like to get in touch with this M1 Garand (only) 'smith, just holla and I'll send you his name/address/phone.
