45 Super round. I just traded in my S@W Shield 45acp for a Glock 21sf 45acp. I have converted it over to shoot the 45 Super round. Purchased a barrel from Lonewolf distributor,s because the barrel is set up tool encapsulates the primer end stronger. Replaced the spring and rod to a 24lb spring and tungston guide rod. Changed magazine spring,s to have a 10% stronger up push.

Underwood is now back into the 45 Super ammo. and also plan,s to invest to build regular 45 Super handgun,s.
Now I can shoot the 45acp, 45acp +p , 45acp +p+, and the 45 Super round.

Example: 185 grain hp round leaves the muzzle of a 5" barrel at 1300 fps.

Drop me a message if you would have any question,s on this subject.
 
I tried shooting 45 Super in my Glock with very poor reliability. Even with two springs in the magazine it would routinely eject the fired round and close on an empty chamber. The slide was moving too fast for the magazine to move the next round into place. Oddly, my 1911 with a Clark 460 Rowland conversion doesn’t have any such problems. I think it must be because the forward thrust against the compensator reduces the slide velocity quite a bit.

I bought a compensator for the Glock barrel but I haven’t gotten back around to giving it a try.

Where did you learn that Underwood is planning to build 45 Super handguns? Thanks.
 
I use a Springfield 1911 with a 28Lb. recoil spring. Works just fine.

Where I got the 45 Super info. was on the Glock forum which presently on this subject as of yesterday was on 93 pages of discussion. The reason you were trapping the cartridge in the slide is because you need to go to a heavier magazine spring. Here is a you tube website for a conversion of a Glock 21 to 45 Super. . You can cut and paste this address in needed. .
 
When I get a chance I will post the type of spring,s I purchased because of the forum suggestion. I believe it was from Brownell.There were 3 spring,s in the package with each having a 10% more push..Another though is if your reloading the jamming will occur if you get roughly above 1.230. I set my reloads to 1.220. Using Starline 45 super brass.

Wolff extra power magazine springs. I bought a pack. Installing one didn’t work. Installing TWO didn’t work. You haven’t seen a hard to load magazine until you try one with two springs installed in tandem.

I can’t remember what recoil spring I used but I’m pretty sure I went with a heavier one.
 
I sent an email to Underwood Ammo Co. and this was the reply: ok this was dated 2012 on Glock Talk. But underwood and Buffalo Bore have plenty of ammo.

Ronald,

That is definitely a round we will be releasing. We are currently looking
into test firearms for the 45 Super. May I ask what you use and if you know
of any drop in conversions for either a Glock or a 1911?

Thanks!
Kevin

So, things are definately moving in a positive direction for 45 Super!
 
Regarding my previous post, the guy had much better success with the Extreme Pentrator in his Glock's rather than the hardcast.
 
I have a Springfield V-16 long slide 1911 pattern pistol.

It’s been reliable with Super, +P and standard pressure .45 loads.

I still have a couple of boxes of .45 Super I bought off The Sportsman’s Guide ages ago... and a fresh box of 500 Starline .45 Super cases I need to find time to reload...
‘It’s a great round and does bring a bit more ooomph to the plates and pins over the regular pressure loads for sure. It would be great to see it come back from the scrap pile of good, but unpopular, cartridges.

Stay safe!
 
I have a smith 4506 that I have been researching the steps to run 45 super. I have been leaning towards sprinco for the recoil spring.

http://www.sprinco.com/springs.html

I have been running some hot 45 acp reloads through it without any problems with the stock spring.
 
The 255 Grain hard cast lead by Underwood or Buffalo Bore would be a good woodsman carry load that is if the Bear spray did not not work. / Ya know, N.Y.S. Bow Hunting regulation,s say: You can carry a handgun with you when you hunt Deer BUT you cannot Bow hunt for Bear and carrying a handgun ???
 
Duke, that sounds ok on the stock spring working for you. Are they fairly new ? The only problem I can conjecture would be when you go to a stronger return spring because of the much hotter round the 45 Super would be. It.s like a 45acp +p+. ?

I carry a S&W 25-2 sometimes when I go hunting and I keep it packed with those Buffalo Bore loads. It’s a fine gun and when coupled with the 45 Super I really like it for a hunting woods BUG.

It's called a case head, and the design of the LWD barrel you're referring to is known as better case head support.

Why? The guide rod is stationary; making it heavier doesn't increase slide assembly inertia, just makes the gun heavier. If you want to add weight to soak up recoil, lead slugs in the grip are more practical and economical.

You need to become more educated on the subject yourself before you offer to answer other's questions. Do you know what the difference is between .45 ACP brass and .45 Super brass without Googling?

The 4506, especially the even beefier 4506-1, really doesn't need any alterations to run .45 Super. If it's gonna be a steady diet, a stouter spring is a good idea, though.
 
Found this reload Chart for the 45 Super. (Remember to use caution) and start low and then work up . Back off if you see any sign,s of pressure indication,s. This is just for reference only .Always use Starline 45 Super brass unless you know of the same type brass of sound construction from another manufacturer. Also they recommend when reloading for the 45 Super to (not) use the magnum primer,s.

http://www.handloads.com/loaddata/default.asp?Caliber=45 Super&Weight=All&type=Handgun&Source=

Powder that I have seen mostly used is Power Pistol, but I have also seen being used with good results but with lower pressure,s to achieve the same results is the IMR 800X. I do not have much of any info. on the 800X, I would need to do some researching on this powder use.I have only heard of this in a discussion on the 800X powder but not much as far as reload data.You can find other good load on the Glock forum web site I posted.. Also if you check on You Tube there is a way to convert the S@W Shield 45 acp also. But I decided to trade and get the Glock 21sf. I am presently also looking for a compensator for it.

Also a comment on changing to a heavier spring I researched, Most of my readings were that the 24lb. spring on the slide was best for most people, to convert to. a much lighter spring would have had the slide beating up the gun and to a point of causing damage to the semi-auto... The 45 Super brass sold by Starline is a much beefier brass to handle safely the higher pressures. The length of this brass is no different that the standard 45 acp brass.
I,m outa here for now. But if any one has some good tested reload information , please post it. thanks guy,s.

Yes , I mentioned the hard cast in my thought as only to carry as a woodsman load for protection for Bear,s. Which I hope nobody get,s into that kind of problem. Also it,s a through and through Pig load for those who hunt pig,s.
