Early 70s I got new 1911, S&W 39 & Brn HP.- same day. Using
all FMJ factory ammo the 1911 was the looser on accuracy, m39
second, Brn HP first. This was off a rest. The m39 was easier to
shoot offhand because of the sights. The HP was smoothest by
far. The Colt 1911 was the worst trigger of the 3 and had added
minus of the stock sights. That's just comparison between these
3 pistols out of the box.

Not long after I got these pistols I got a case of Military 9mm
that was hot for open bolt SMGs. It was foreign ammo and I
didn't realize what it was. I was shooting the 39 more than the
others and cracked the frame on 39 with this ammo. I didn't use
it in HP because it wouldn't fire without dropping hammer on it
twice. The 1911 are it up, no problem. I quit shooting it in any
of my 9mm after cracking the 39 and finding out what it was.

All three of these were top rate pistols and were more than
capable of what they were intended for. I'm not bad mouthing
1911 ( Colt) or 9mm cartridge. I would carry a 1911 and think
it best combat pistol ever made. If I carry one it will be a 45
for weight & size why not.
