The thumb safety on an M1911 rotates up into a notch in the slide and locks it in place, so you have to flip the safety down and OFF to rack the slide to unload.
It's very well optimized for a fast and accurate first shot, at the expense of needing more care than later designs to unload.
9mm and .38 special are basically the same caliber. The 9mm is .355".
Assuming the rounds are the same type (both FMJ, or both JHP), Any difference between the two would be in bullet weight and velocity.
Most people firing the 9mm use bullets in the 115 gr to 147gr range. ballistics101.com gives velocities for the 115gr at about 1200-1300 fps, slightly slower for the heaver bullets, for typical muzzle energy in the
300-400 ft-lb range.Most people firing the .38 special use bullets in the 125gr to 158gr range, with velocities in the 800-1000 fps range and typical muzzle energy in the 200-300 ft-lb range.
The numbers indicate that while the average 9mm bullet may be slightly lighter than the .38 bullet (the range of bullet weights actually overlap considerably), the 9mm's considerably higher velocity makes it a heavier hitting cartridge than the .38 Special. A web search on "9mm vs. .38 Special" will bring up a number of sites that compare the two and come to the same conclusion. And a +p+ 9mm increases the difference even further.
Now, the .357 Magnum is a whole 'nuther story. Same diameter bullet as the .38, but with heavier bullets than the 9mm (the most common being
158gr) and also higher velocities (1200-1600 fps), it has a typical muzzle energy in the 500-700 fps range, nearly twice that of the 9mm, and more than twice that of the .38 Special.
Sez who?

Then there are the .45 long Colt rounds at 325gr and 1300+fps muzzle velocities! Muzzle energy of 1260+ft.lb. !!!
I like my Judge! If it won't stop a guy, he probably needs to be run away from, not shot again!
I fell in love with .45 rounds in 'Nam, where despite the velocity and accuracy in clean air, the 5.56mm rounds were just about useless in the bush. Any little thing would deflect them. I ended up carrying an M3 Grease Gun for the latter part of my tour. Low velocity rounds, yes. Good penetration in heavy cover, yes. Like throwing small, very fast rocks!

FOR THE MILITARY round nose, non expanding bullets are the rule.

For the average grunt, yep. Special units usually choose their own rounds, even if they have to go buy them off the civilian market.
And don't forget that as far back as Viet Nam, we knew about notching the tips of 'special' rounds.

Sorry bout that, cat walked on the keyboard as I clicked send.
She can't spell worth a damn either.
??? Don't tell my XD or it will want some of that fancy shit rather than the 115 LRNs it usually gets.
Cheese moving noted. But, if you really want to go down that road, the Cartridge, Caliber .38 Ball, Special, M41 has in use for aobut 50 years to meet the requirements of land warfare. It's a 130 gr FMJ.
Yeah, M41 130 gr FMJ is the military round. I doubt it breaks 800 fps. M882
9mm ball is 112 gr at 1263.
He might have never met a .40 S&W. I know quite a few people with .40s. Why? It's a USPSA major caliber and 9mm is a minor. In other words it's gaming the scores when puching paper. I shoot Production where everything is scored as minor so I never bothered. Personally, I hate the damn things; when someone else is picking up your brass they tend to slip in a few .40s. Close, but no cigar when you try to run them through a progressive press.
Why do you say that?
I'd gave to dig around to find it but there was a more recent study. iirc the gist of it was if you want a one-shot kill, a handgun isn't a real good option, but that's been known for a long time too.
They might as well standardize the magazine first, like was done for the
30 round M16 mag.It's almost impossible to tell one 9mm/40 double stack mag from another if they aren't marked. Everybody's trying to reinvent the HiPower mag.
Keltec designed their P11 to use any S&W 59 series mag that held at least 10 rounds. That's a start.

A rather nice round for self defense in .38 Special is 110gr +P.
difference
Keep in mind that the .38 Special also comes in +P and +P+.
Although the most consistent load per FBI results is the 125gr.
and also higher velocities (1200-1600 fps), it has a typical
Yes, and higher chamber pressures than either of them.

My most often carry gun is a Ruger SP-101 in .357Mag loaded with rounds from Federal Hydra-shok or Buffalo Bore. During the super hot days of summer in Arizona, I can drop down to .38Special +P as the thickest upper clothing worn is usually a worn T-shirt or a tank-top. Lot less flash and bang in a snubbie.
Yes, humans are rather soft targets.
That's always seemed like a strange loading to me. Most older .38 revolvers and some if the newer aren't up to +P loads. otoh, a SP101 with a 2.25" barrel is hardly bulkier than the traditional .38 snubbie and handles ++P++, aka .357 Magnum.
Good luck with that. It pissed me off when Springfield Armory came out with the XDM that is not compatible with XD mags. Of course, if they did standardize, someone could make inexpensive generic mags like they do for the 1911. Where's the fun in that if you can sell your proprietary mag for $30?
