BUT, +P is their absolute limit; or so I heard.

Dont know what they might use for an "over pressure" proof load, or even if they do.

Also heard that +P+ was total a no-no, but then, supposedly, its also over SAMI specs.

Read Pat Cascio's review on Survival Blog. He used +P+ loads in it towards the end of his review. It ate them just fine. Would I do that?? Heck no! But he did. And they are supposed to shoot a proof load in it before it leaves the factory. If they aren't doing that, shame on Remington.

Dont know if the lack of support for +p+ loads is lack of strength or Remington not wanting the liability or warranty claims. 

A stiffer barrel spring could help bring the limit up a bit.  Or at least thats what is recommended for my makarov when shooting 115grn bufalo bore.  Grandma might not be able to rack the slide, but whatever.

So, i could potentially change my barrel, breech block, main spring, and magazine and convert my 9mm gun to 357 sig then?

Oooooo, how about .22 TCM?! Would that just be the barrel, maybe the spring?

Engineer Power,
.22TCM? Surely you Jest!

.22 TCM certainly would be an easier conversion here than .357 Sig!

And more beef left around the chamber.

But my question would be, would the AL frame take the beating from the breach block?
(Which also might have a problem here)

[mr220v]

.22tcm is a good bit longer than 9mm or .357sig.  The r51 frame would need a redesign to accommodate that one.

There's the 9r bullet profile made to fit standard 9mm mags.

But my question would be, would the AL frame take the beating from the breach block?

From what I understand, .22 TCM has ~40% less recoil than the 9mm, which would be easier on the frame than its default chambering.

.22TCM cartridges are about twice as expensive as 9MM.   Not a good upgrade
expense wise.

There is no SAAMI spec for +P+. 

SAAMI specs max pressure for 9mm Luger at 35,000 max and +P at 38,500 max.  Anything over 38,500 is "overpressure" for +P  it could be 38,501 or 38-bazillion.  None of it is SAAMI spec past 38,500.

Maybe not an endeavor in economics, but I bet this little gun would make a sweet rocket-launcher, and would reduce the already-low flip to about nothing.

And besides, I happen to know there's at least one regular on here that's also on 22tcm.net

I know that TCM is more expensive, but if you reload it'd be more economical.  I think that it's a pretty neat cartridge.

Setting this gun up to shoot anything but 9mm will drive up ammo costs. 

The shorter tcm round is a good idea.  Just a barrel change.  Maybe a spring change.  Would probably bring muzzle flip down to almost nothing.

[Chokejug]

Hey, the more I hear, the better the TCM idea sounds!

With the "short magazine load", (for Glocks, Bobergs, etc), the feed problems with the lousy magaznes might just go completely away.

At SD range, it should perform at least as good and likely better than the FN 5/7!

And if the bullet dont "get 'em", the muzzle blast will!
