Is it an ECB or an offset? if you have an ECB get a 55 gal drum and cut the heads out and slip it over the pit I used to do that in N WY when I Cowboyed up there in the winter ECB thought it was in Miami when it was -20 with a 30 MPH wind.
if its an offset a doubled up movers blanket from Harbor Junk will fit your pistol.
