Taffin's article:

What is a
.460 Rowland?

It is simply a .45 ACP case that has been stretched and strengthened. Starline is making the brass, head stamped .460 Rowland." It is .0625" longer than a .45 ACP- standard .45 ACP reloading dies work- and features a beefed up interior. It will not chamber in .45 ACP guns, nor will the .460 Rowland fit in a standard .45 ACP. Double action sixguns chambered for the .460 Rowland will accept .45 ACP rounds by using half or full moon clips. Caution! Some early 1917 revolvers are chambered straight through and they may accept .460 Rowland rounds. It would be a disaster to fire this hotrod round in these old, weak sixguns!

Q:What 1911 pistols do you consider the best platform for the 460 Rowland Kit?
A: The best candidates for this kit are STEEL FRAME single stack Springfield Armory(including current production GI & Mil-Spec models), Sig Sauer, Colt, Smith & Wesson, Para Ordnance, Kimber, Norinco, Dan Wesson and 1911 style 45 ACP semi-auto pistols. We prefer and recommend Blued guns over Stainless. Preferred Gun List
Q: Why does it make a difference that my gun is stainless?
A: MOST Stainless steel creates a great deal more friction than traditional blue (Chrome Moly) steel. We have found that most stainless guns will not work with the 24lb Wolff spring that we normally ship with the kits. Always try the 24 lb spring first. If it doesn't function reliably, switch to the lighter spring we've supplied. If it's still not functioning, Please call us for further assistance. Please note that many Kimber 1911s are stainless steel although they may appear to be otherwise and all Para Ordnance Expert Models are Stainless Steel.
Q:  Do you make a comp kit to fit my Colt GOLD CUP/ENHANCED model? Colt 1911 45 ACP Gold Cup Colt 1911 Enhanced Model 45 ACP
A:  YES..  The Gold Cup / Enhanced Model Colt 1911s have a slightly different barrel hood.  Please make sure to specify GOLD CUP / ENHANCED model. 
Q: I live in a state where the compensator must be permanently affixed to the barrel. Should I send my slide to you to have the kit fitted prior to permanently attaching the compensator?
A: Absolutely! The most likely outcome of buying the kit without us having your slide is a larger than necessary gap between the comp & slide.
Q:  Do you make the drop-in kit for my Para Ordnance?
A:  Sorry, we've discontinued the ramped model which fit the Para Ordnance P-14. . Good News is that Para is now making the Expert which will take our standard Kit (also fits in older GI Expert Para Ordnance)
Q:  Do you make the drop-in kit for any 1911 shorter than the government model?
A:  No: Commander (4.25" barrel) kits have been discontinued.
Q: Can I buy a .460 Rowland Conversion kit without a compensator from you?
A: No
Q:What if my drop in kit doesn't drop in?

A: Send the entire Comp Kit, your slide and $ 20 (Return Shipping & Handling) to us for a complimentary fitting by our gunsmith.

Q:  Where can I get .460 Rowland ammo / brass?
A:  Right Here @ Clark Custom Guns Call us @ 318 949 9884 M-F 8 am - 4 pm CST to order.
Ammunition Manufacturer: Georgia Arms AND Buffalo Bore
Q: Will .460 Rowland Ammunition fit in my factory .45 ACP magazine?
A: Absolutely!
Q: Which Magazine brand do you prefer for the 460 Rowland?
A: If your factory mags aren't feeding reliably, our "goto" magazine is the 7 round Tripp... available from us @ $ 34.95.
Q: Which recoil spring should I install?
A: Always try the 24 lb spring first. If it doesn't function reliably, switch to the lighter spring we've supplied. If it's still not functioning, Please call us for further assistance.
Q: Should I install the extra power firing pin spring?
A: Asbolutely
Q: How long is the compensator?

A: 1.5"

Q: What is the overall length of the comp kit?

A: 6.5"

Q: Do you know of any holsters available for my 460 Rowland 1911 pistol? Diamond D Custom Leather Guides Choice Chest Holster

A: Yes. Diamond D Custom Leather will make a holster for you. We particularly like their Guides Choice™ Chest Holster

Q: Are there any other guns that you specifically DO NOT recommend for the 460 Rowland?
A: YES! We do not recommend this kit for installation in
  • Metro Arms American Classic
  • Armscor
  • STI Spartan
  • Tisas ZIG
  • IAI (Israeli Arms International) - We've found the top lugs in the slides of the Philipines produced 1911s to be soft! We've not tested the Israeli made guns but would recommend extreme caution.
  • Rock Island Armory
  • Auto Ordnance
  • Taurus
  • Llama
  • AMT
  • Charles Daly
  • Essex
  • Remington Rand
  • Any "GI" 1911 (pre-50s / spot heat treated)
Q: Is it safe to install the 460 Rowland Drop In 1911 Comp Kit into my older spot heat treated 1911 pistol?
A: NO! We do not recommend this kit for installation in any GI or other spot heat treated 1911s!
Please note that we will not guarantee this kit to fit or function in your Auto Ordnance, Llama, Charles Daly or AMT 1911 style pistols nor do we recommend these as platforms for the kit.
Q:Will shooting the 460 Rowland in my 1911 increase wear on my gun?
A: Any time you increase power, you will accelerate wear. For example, you would expect more wear on your revolver if you were shooting a steady diet of 357 Magnums as opposed to .38 Special loads. We've sold over 1000 of these kits with no reported stress related problems.
Q:  Will you chamber my non-compensated barrel in 460 Rowland?  OR sell a barrel only (No Compensator) in 460 Rowland?
A:   No,  the compensator is necessary to prevent damage to your 1911 pistol.
Q:  Can I still shoot 45ACP in my gun? 
A:  We do not recommend shooting .45 ACP in the 460 kit. 
Q: Do I have to buy new loading dies?
A: No. You can use your 45ACP dies to reload 460 Rowland.
Q:  Can you provide a cylinder chambered in .460 Rowland for my Smith & Wesson 25/625 or Ruger Blackhawk?
A:  No, you must currently send in your cylinder assembly to be rechambered. (Click here for more info)
Q: Can you make a general comparison between 460 Rowland & 45 Super?
A:  200 Feet Per Second faster.  460 Rowland brass is longer and supposedly more durable.  460 Rowland will NOT fit in a 45ACP chamber!!!

Video (Note: Toll Free Number on Video no longer in service)
Q: Which Recoil Spring should I use with the 460 Rowland Kit?
A: You should start out with the heaviest recoil spring supplied with the kit (24 LB) wolff spring. If it's too heavy, change to the 20 lb spring also supplied with our kit.
Q: Brass is failing to completely eject / extract?
A: Try a lighter recoil spring.
Q: Should I install the Extra Power Firing Pin Spring that comes with the 460 Rowland kit?
A: Yes.
Q:What if my drop in kit doesn't drop in?

A: Send the entire Comp Kit, your slide and $ 20 (Return Shipping & Handling) to us for a complimentary fitting by our gunsmith.
