Carguychris, Good post. You are most correct that some of the old M20's were reamed out for 357 mag by Police agency's on a budget. The gun was almost a M27 when came down to it. I would not shoot 357 in that gun either unless I handloaded 357 brass to a hot 38+p MYSELF. I have reamed out and rechambered guns and I was never happy about it in the long run. I have a Pre 64 M94 that was reamed out and lined to shoot 38-55, I thought I had to have a 38-55, now I wish it was a 30-30 again
That gun is kind of a period piece like when Swenson put S&W adj sites on 1911's, I would leave it like it is and shoot it. It should be a pussycat with 38's in it. It would look good in one of those old Sam Brown rigs with Nickled 38 bullets in loops all over it. Kind of like a Bad ass Barny Fife rig, like Bill Jorden had. I could see Bill Jorden all crouched down DA shooting it one handed at a bunch of Beatniks with peace signs.........................PTSD attack coming on
