I shoot its big brother (460 rowland), tons of fun! From what i've read you can get right up there with the 45 super, but you and your gun better be prepared for it. I've seen this done mostly with 1911s, but i know glocks and xd's can also be retrofitted. i only opted for the 460 so i wouldnt accidentally load one into my 45 bbl, that and i got a really good deal on it... -
I shoot 45 Super from my G21SF, G30SF and a couple of 1911's. Basically heavier springs. They work and shoot fine. The only caveat is I would not shoot them from a family heirloom 1911.When asked what qualities he most valued in his generals, Napoleon said, "give me lucky ones."Comment

No, 45 ACP is good enough.

I shoot 450 SMC which is a 45 Super with a small rifle primer. Double Tap Ammo is the only factory loadings that I'm aware of. Presently I shoot it in a Colt 1991 with 10mm grade springs.
The small primer supposedly eliminates primer blowback/rupture which is a risk with the Super.
I'm skeptical of the survivability of this round.
I plan on getting a heavyier recoil spring for my full size HK USP 45 when I get it and try the 450 smc in it. the HK is in jail until the 5th of Jan.Comment

I have been in lust w/ the Underwoods 230gr XTP 45Super load in my sw 625 JM for a year now.
They really bring out the performance of this piece w/o beating it up.
My Glock 41 runs them well w/ a 22lb RSA and it feels like a real weapon now instead of a target plinker.
I think everyone who shoots a full size, modern ACP weapon should consider Supers for their high-test fuel.
They perform similar to commercial 10mm's in the 180/185 class (1300fps).
I don't think I could reliably operate any greater recoil.
It's great that I don't have to roll my own to get this level of performance.
Port.

I wonder if it would be crazy to try to shoot them out of a Tanfoglio 45?Comment

I have heard you want "more supported" chambers than what a lot of guns come with.Comment

oh gawd... someone heard something again. sigh.
g21 .460 rowland. Amazing amount of power in that combo. Stupid assault weapon laws make things tougher to deal with. Can't have a thread on brake so have to use an extended and ported barrel and heavy springs. Not for kids, people with weak wrists, or anyone afraid of recoil. To me it feels like getting slapped in the hand with each trigger pull.Comment

The only mods I have done to any modern 45 Auto chambered guns that I shoot 45 Super in is heavier springs. In the case of my G21SF, I run a 22lb RSA, in the case of my 1911's I run a heavier 22lb recoil spring and a heavier main spring. The main spring is the most important as you get the "slow down" power without having to add too much "slam back power" of the heavier recoil spring. In any case, hotter 45 Super is pretty hard on any gun designed for 45 Auto. For the occasional outing with a gun you are not sentimentally attached to, heavier springs are all you need. If you have a $5000 Wilson Combat you plan to keep for life, I would not feed it a steady diet of 45 Super, at least not top end 45 Super (anything above 1000fps for a 230gr slug).
Aftermarket barrels can add value in some ways. Typically with hotter handgun ammo, the longer the barrel, the more a round will shine. This is definitely true with 10mm and 45 Super, etc. The magnum style (slower) powders used work far better when the barrel is longer. I have seen more than 100fps difference in the exact same load comparing my stock length G21barrel, versus a 6" hunting barrel. Aftermarket barrels also tend to have a little tighter chamber than say a stock Glock chamber (less the case with many 1911's). The tighter chamber will yield a few more turns on your brass life if you are reloading.
The argument for "more chamber support" is valid if you are loading in the twilight zone (way above SAAMI pressures). An aftermarket barrel with a steeper feed ramp (less incursion into the chamber) will allow slightly more powder charge before you start seeing smiles on your cases (in any case, if you start seeing smiles, you are waaay past SAAMI max pressures or something is not right on your gun).
If you are shooting ammo loaded to SAAMI spec maximums (commercially loaded ammo or reloaded to powder or bullet mfg published maximums), there is no need for an aftermarket barrel in any gun I have ever shot 45 Super.Last edited by Bill Steele; 01-01-2015, 10:00 AM.When asked what qualities he most valued in his generals, Napoleon said, "give me lucky ones."Comment
