Why The .45ACP?

[Army 1911]

Yea, we also kinda used a nuclear bomb.....still waiting for my tax stamp on one of those!

Really? We nuked Germany?

Defeating Germany did not end WWII.

No, but we didnt 1911 them to death either!

Is the SAR K-2 based on anything? I had to look up what that was and it has a certain CZ-75 aesthetic.

Sar are almost all based on CZ models. Great Turkish firearms.

How much is the difference, then?

Assuming a max expansion of twice the original/bore diameter, nearly a quarter-inch. 9mm max is around 0.7", while a .45 would be 0.9". Tenths of an inch, not hundredths.

I carry a 1911 in .22 TCM.

19 rounds with the recoil of a .22 mag and the knock down power of .45 ACP.


The hydrostatic shot alone is enough to remove limbs.

Isn't the TCM something like 2/3 the velocity/energy of a comparable weight in a 5.56 rifle? 39 grains at just shy of Mach 2 out of a 1911 sure as hell ain't something to sneeze at though, that's for damn sure.

Edit: Looks like the TCM is closer to 1/2-2/3 the oomph of a comparable .223/5.56 load from a rifle(3,200-3600 FPS). Still damn impressive.

I did not think it was that much of a difference.

In the BEST of scenarios that equates to .1" on either side.

It's easily made up for by having 15rds in a mag versus 8rds.

Correction: That equates to .1" on BOTH sides!

As you can see the difference is about 1/10 of an inch in width.

It's a pretty hot little round.


I don't carry it, but I damn sure don't want to get hit with it either.

I ran mine across the chrony and was getting 50-100fps higher velocities than advertised. Still not a 5.56, but surprised to see a round put out better real world numbers than advertised.

Having observed those results, I was just as surprised. I've often wondered about it as a carry round. Would the extra penetration, potential shock, and negligible recoil make up for the (possibly permanent) hearing damage? That is one LOUD little beast.

As you can see the difference is about 1/10 of an inch in width.

Or, in relative terms 27% larger in diameter.

And normally 56% to 100% heavier. (115 to 147 vs. 230 gr.)

[TexasBrandon]

Not really sure why someone would use a 230 grain when 185 grain works better in terms of energy, unless your using +P ammo.

 

[XinTX]

Do you want every exception to every general rule listed?

Guess some people are so simple...

Yeah. It makes a mess of the spreadsheet.

Graphic content, but because you insisted....

Hahaha! Damnit, now I want a TCM.

Great job YG!
