Who makes the toughest .45?

What .45 acp's can handle a steady diet of +p ammo?

Most manufactures don't recommend a constant diet of +p.

What manufactures stand by their pistol and say that +p is fine?

The HK Mark 23 and the HK USP .45 were designed around the same time and were made to take the heat. Though +P does obviously cause more ware than less potent loads these two handguns are for sure made to be able to go +P without a problem.

-- The more recent HK45 probably was built around the +P as well but I've not researched or shot one.

+ Some people have even started shooting .45 Super in their USPs. Though, I personally would never ever do that even with a spring replacement in any gun.

EDIT: And to say it right, I would say the toughest .45 I've seen/heard stats on is the Mk23. If you google it you'll probably find a lot of info about specifics.

I'll agree with CZCASULL, the HK Mark 23 will take the heat. I shoot both 45ACP and 45 Super with spring changes of course thru my Springfield Armory longslide V16 marked and made for 45 Super. Had to do a little fitting on the slide and frame to make it run smoother but she runs great now. There is one for sale now on Gunbroker Auction # 179122988 . Although, I do not know if this one is actually marked 45 Super.

Oops

Just read the entire first post and noticed to +p part. Must have a case of diarrhea of the keyboard. Feel free to disagree.

I would think a quality forged frame/slide 1911 would stand up to a steady diet of +P .45 ammo. Simply use a heavier recoil spring and maybe mainspring. Add a shock buff if you want for range work. They make 'em that shoot 10mm all day so +P .45 should be no problem.

Well, they will accelerate wear. That's just a fact of life, like driving a car at 80 mph instead of 50 mph.

Not a Sig and not a G21. Although a +P .45 is lighter than a .45 Super, a steady diet of +P would take a toll on an alloy or polymer frame over time. Guns like the Ruger P90, S&W 645/4506, the HK's, and CZ-97's would probably hold up best.

Good reading here:

You ain't gonna like the answer....

Because its out of production, and is too big for CCW or even a duty holster gun.

LAR GRIZZLY

Conversion kit to .45ACP. Any gun built to handle the .45 Win Mag will take a steady diet of .45ACP +P without even noticing.

Second answer, still in production, but not an automatic, the Ruger Blackhawk .45 convertible using the .45ACP cylinder.

I don't know of any maker who will state their .45 auto will take a steady diet of +P ammo. Some of the guns will take it better than others, but no maker will come out and state that.

It's Super-Dave, he suffers from CEPD ( Compulsive Expansion & Penetration Disorder)
He usually want's to know what shoots through windshields, car bodies, plywood, doors, etc. You know, all the things you run into in everyday self defense.

The performance of ammunition has decided the fate of soldiers for a very long time. Self-defense is no different. You can only be as prepared as you can be.

I'll second the Ruger P90/S&W 4506, as well as the Ruger revolvers chambered in 45lc/45acp. Maybe even the S&W 625/325, and probably most steel framed 1911's.

Ruger P-90 has to be considered as well as the discontinued 4506 series of pistols from Smith&Wesson. The Glock will do just fine as well. It was designed around the 10mm and has proven it can take the hottest 10mm rounds better than any of the competition.

There is only "one" tough .45 caliber pistol class...

Any Glock in .45acp or GAP.45. Period.

All else, is foolishness.

6.8, out...

Here is me, firing my Glock 21 with +P .45 ACP rounds:

Who makes the toughest .45?

If anyone lists a 1911, I will beg to differ. Having recently studied the design, timing, and lock-up of the 1911 design, including the information on the 1911 forum and information from the very knowledgeable Kuhnhousen, a factory produced 1911 is most likely to be a "link rider". As such, the link will fail prematurely and sooner with +P ammo. The information also strongly suggested that the only way to be assured that the 1911 is operating correctly (in time, not riding the link), is to have a custom 1911 fitted with the bottom lugs doing their caming action (instead of the link), as designed by Browning.

MY question stems from intrigue, not contempt. How is it that Ace Custom .45s Inc. is able to put out 1911s that reliably fire .45 Super?

Freak -

That looks more like a Kaboom to me

My natural inclination is to vote for Hi-Point

but I would feel as if I was betraying my Ruger P345, which is an extremely rugged weapon. Maybe a tie...
