+1 to that brother. I do my own 'buba' work, and use a 'buba' test for winter environments. I take it to my range in mid-winter (well below 32 degrees F) and set it out on the bench for several hours while I shoot, or relax in the clubhouse..... After unprotected hours in the cold, if it shoots various junk ammo and factory stuff without a hitch, I expect (hope) it will hold-up. Needless to say, if I carried for SD, I would not 'gunsmith' anything.
IMHO of course,
