The problem is all about the legacy of .38 Special. At its heart it’s a black powder cartridge which limits the pressure to 17000 psi. All the FBI and police loads were loaded way beyond this pressure limit. While this put undue stress on the guns and limited their lifespan the Colt and S&W revolvers being carried by the police were capable of handling this. Even then shooting Winchester 110gr +P+ which is likely running 23-2600 psi is only moving at 1100 fps out of a 4” barrel. Compare that to Winchester 124gr bonded moving at 1150fps from a 4” barrel.

The pressure is both a pro and a con. One one hand MODERN 38 revolvers are almost all +p rated, so that old Remington FBI load won't do damage.

It's one I personally carry, and with that 158 grain round and it's kick, even out of my old style model 36, which can take a little +p if you don't push it, used as a duty load, even with its 1.75 inch barrel, and with FBI experience, it's going to flatten a man. That's raw statistics from decades of use.

Another pro is the low pressure. Even with +p, it's still 10000+ less than 9mm. As long as you either have a +p rated 38, or better yet, a 357 revolver, that sucker can and will last 100 years, if the surviving guns are anything to go by.

You are right on power. As good as the FBI load is, 9mm IS better terminally when both have a 4 inch barrel, and it will have more stabilization. Not to mention a lighter bullet and less brass. And it CAN be chambered in revolvers to quite high capacities with the aid of moon clips.

I have watched that show multiple times and never realized that those were longslide M9s. I always assumed based on the trans that they were just FS chrome or Inox.

My original plan was just to get an Inox with some engraving and special grips.

Now I want a longslide M9 though, and probably wouldn't do anything to it aside from potential spring changes, but it sounds like those were competition models which probably had better trigger weight to begin with.

Edit: ah...competition long-slide kits...which don't look anything like the sword cutlass. I think I still want one but not as much as a Q5 Match SF if we're talking thousands of dollars in a pistol lol.

Speaking for me, I just want a M9. The beretta will always be the sexiest 9mm on the planet. And 17 rounds stock is plenty for a duty gun.

I've been eyeing up the m9a3 in the local stores. I do like the FDE and all the improvements over my 92fs that I got years ago.

In addition, anyone ever use the 32 acp replacement cylinder on a nagant revolver?

 

[HarblMcDavid]

I know your pain. Come to me when you get the gut punch of knowing that your chances of getting a 6 o clock revolver like Vash the Stampede limits you to the Rhino. XD

Don't get me started on fucking Matebas.

I really want a 2006M with all the different barrels, but they are a bit 5k-10k, and mostly in the hopes of producing CAD models to make reproductions. Those things are super fucking cool.

I'd only discourage you from this if you have small hands, otherwise it's my favorite pistol I've ever shot (once I did the hammer spring change), assuming you're okay with a gun that weighs a shitload.

Edit: it's also frankly, beautifully engineered. So many things just fit together and retain each other perfectly without needing screws or roll-pins. Reminds me of the Benelli shotguns in a lot of ways.

Learning, after I started tinkering with my 92F compact, that you could detail strip the entire thing with nothing but a flathead (for the grip screws) and a 1/16 punch really increased my appreciation for the 92 design–They're a joy to work on. That being said, while the frame is IMO essentially perfect, the slide has some quirks that can be kind of annoying, specifically regarding the safety/decocker and extractor:

The safety was seemingly designed by a man with three hands, as to remove/replace it you have to depress the firing pin block upwards from the bottom of the slide, while also pushing in on the firing pin, while also pushing the assembly in/out. Putting it back in is the worst part, because you also have to perform a balancing act with two tiny pins under spring tension that like to go flying off into another dimension if something slips.

The extractor is easy to swap in or out, but needing to be restaked every time it's replaced is clumsy design that feels out of place with the rest of the gun.

The fact that both of these parts need to be removed to access the firing pin/firing pin channel only adds the the annoyance.

Also, while the fixed front sight blade was excusable in the 70s and 80s, the fact that new production FS models being sold today still haven't had that limitation addressed is retarded. If Beretta were smart, they would capitalize on it by selling 92X RDO slides independently on their website as a swap-in fix, but alas...

Here's another something that tickles my autism just right.... .22 CHeetah

It's .308 necked down (up?) to .223/5.56, and allegedly pushes 4300 fps. That kind of velocity is just nutty, and I love it. Popping prairie dogs would be like zapping them with a laser.

22-250 and 223 WSSM would like a word

22-250 and 223 WSSM would like a word

Close; but my wikifu shows that the .223 CHeetah appears to be on par or faster, and with a slightly heavier projectile than either at 50gr.

What really interests me is that it might be easier to build an AR around .22 CHeetah as well, rather than being limited to bolt guns & single-shot rifles/pistols (i.e. TC Contenders, which I hate). Although it's probably a good idea to have something with a QC barrel for any of these superspeedy cartridges, since they sound pretty rough on barrels.

When they say these are barrel burners you are looking at 200-300 shots before the barrel is shot. For comparison 223 WSSM never really took off due to its barrel life of 300-500 shots. Most consider 243 a barrel burner and you will likely get 1,000-1,500 shots before the throat erodes.

If I was going to build a Semi-Auto for varmint it would be 223 with a 1:12 twist running 40-55gr projectiles or a 6.5 Creedmoor running 95gr if I wanted to reach out.

What a good entry 2-stage drop in trigger?

 

[Deckard Bane]

Speaking for me, I just want a M9. The beretta will always be the sexiest 9mm on the planet. And 17 rounds stock is plenty for a duty gun.

The M9 is a great gun, and while they are a little pricey for a new model they are extremely good quality and will last a lifetime if you take care of them. Hell, even if you don't they probably will last, my 20+ year old service issued one was beat to shit but still worked great. They are significantly heavier than most people realize since they are full size with a metal frame, but while I appreciate the advantages of my polymer frame handguns there is something satisfying about the metal on metal sounds that come out of it when reloading, racking the slide, and engaging the safety.

Rad, it'll make my backwoods railgun larp even more realistic.

If I was going to build a Semi-Auto for varmint it would be 223 with a 1:12 twist running 40-55gr projectiles...

So basically .22 CHeetah?

Granted I have no idea what the twist would be for these rounds circa 4200fps. Things get weird when shit travelling that fast spins too quickly, and I've heard from a few guys into this stuff over the years about jackets peeling off rounds; which is another reason they stick to monolithic alloy projectiles.

I'm just curious what it would take to push a .22 to 5000fps; and if it could be done repeatedly, maybe by using something like titanium (etc) barrels or sleeves.

Edit:
.22 Eargesplitten Loudenboomer

This humorously named cartridge was developed in the 1960s by P.O. Ackley for Bob Hutton of Guns & Ammo magazine, and was intended solely to exceed 5,000 ft/s (1,500 m/s) muzzle velocity. Ackley's loads only managed 4,600 ft/s (1,400 m/s)(Mach 4.2), firing a 50-grain (3.2 g) bullet. Based on a .378 Weatherby Magnum case, the case is impractically over-capacity for the bore diameter, and so the cartridge remains a curiosity. The advent of new slower-burning smokeless powders may have changed the equation.

... or a 6.5 Creedmoor running 95gr if I wanted to reach out.

I love that particular cartridge, or most anything in 6mm now I think on it; but they're still too slow...

Do you mean a cassette trigger where you don't have to fuck around with a 3-armed install? Or just a trigger that's good and can be dropped in?

I was going to say I really like the Geissele SSA or SSA-E (not sure off the dome) and it is everything you'd want besides being a cassette, though I did pick mine up at sub $200 used. Still, crisp, plenty light, and allows me to poke ragged holes if the barrel and I both do our part.

Cassette, something that a new person can work with without a big chance of fucking up.

 

[White Devil]

Gonna second a LaRue. I wouldn't drop dime on a Geissele unless you shoot enough to justify it or you can get an agency to cover the cost.

It's absolutely worth buying a 92 Elite LTT. It's not cheap, but when you see how good the single action reset is and how well the pistol is gone over, I bet you won't mind the cost.

I will say that trigger installs aren't nearly as daunting as they seem, 3 handed comment aside. I did my first one on the dining room table and managed not to cock it up having only installed one mil-spec trigger previously. So don't be too intimidated, but cassettes are just a lot easier.

 

[POWER IN MISERY]

god i did not realize i would like the dissipator this much. maybe it's all in my head but i swear on irons i had better groupings than the carbine that i slapped the romeo5 on. soon i'm putting one of those blitzkreig chevron sight posts on the dissipator to see how i like it. i like the chevron on my saiga's red dot so if it's anything like that i'll be fat and happy.

I say if you're going to be working on AR lowers even semi regularly get a vice block.
