Sent Alan Harton an OM 357 cylinder 2 wks. ago to be rechambered for 45 ACP. He got it and gave me a return e-mail as to what finish I had on the gun. It's for a 357 OM to 45 Colt conversion. Thought I'd let a pro deal with the head spacing and Alan did a pro job. Rechambered the cylinder to 45 ACP and polished the cylinder outside to match my gun almost perfect, reblued the whole cylinder and shipped it back to me. $165.00 total everything. Now my conversion is complete although a floral tooled leather carrying case with a place for ammo and to hold the extra cylinder would be nice for it. Well a big thanks to Alan for such a quick turn around and quaility work.
