Beautiful find Crestone....I too have a thing for those great years at S&W. My carry piece, through part of my first tour in Vietnam in 1970, was a Combat Masterpiece. I hated those grips...(couldn't find a snap on grip filler for the arch behind the trigger) so my shooting with it wasn't as good as a better stocked gun. Later, I locked it up in the commo bunker safe and got a Browning Hi-Power for the increased magazine capacity...and that was followed by an Army issued 1911A1.
They issued a web belt with it, an ammo pouch, and a half a$$ed holster of gov't make. I quickly had a Vietnamese make me up a better holster which fit the gun to perfection...but the damned thing smelt of the urine they had used to cure their leather...but it worked well. The Air Force issued us FMJ .38 Spl rounds with a 130 gr bullet, if memory serves; plus some .38 Spl flare rounds. The idea was to hide out if you were shot down, then signal the Huey's with a flare round, without shooting them in the belly.
The guns were super strong...before going over, I was the range officer at the AF Academy for a cpl of months. On one eventful afternoon, we had a new cadet fire a squib round, then follow it up with 4 more fully functional ones. The gun tied up on the last round and would not allow the cylinder to swing out...the last bullet had lodged between the cylinder face and the forcing cone at the barrel's rear, and the squib had been pushed up and was sticking jauntily out of the crown.
Our gunsmith tapped them back down the barrel enough to allow the cylinder to swing out, then tapped the rest out though the frame cutout. After a careful examination, the gun appeared unharmed and I fired a full cylinder from rest at the 25 yd target, getting a 3" group...about the average for those well used guns with contract ammunition.
There was no bulge in the barrel or cylinder and we surmised that the pressure buildup bled off through the cylinder gap before anything could happen.
Yours is a beautiful piece of history, well worth what ever you paid. Thanks for allowing an old man's ruminations...Rodfac
