I know that this is stating the blatantly obvious, but I feel that I must add this disclaimer to my thread: In my opinion, under no circumstance, should you convert the original Glock barrel to .460 Rowland! The Glock barrel does not have the proper support for the extremely high pressure .460 Rowland. Use only an aftermarket barrel with a "fully supported chamber". This is plainly stated in the remarks of Johnny Rowland, engineer of the .460 Rowland at 460rowland.com. And it should be well known that even 45 Super can cause a KB in an unsupported Glock barrel. Well, I finally made the plunge. I ordered some 460 Rowland from Georgia Arms. Even though they are 7 to 10 days behind on shipping, it will come soon enough. I am still waiting on a custom engraved 5.2" 45TH from LWD. I think I will have the 6.61" I already own reamed for 460 and leave the 5.2" for 45 Super. I don't know what to expect from the LWD compensator when it comes to the 460 but I will be finding out. From what I can tell Johny Rowland is using a basic aftermarket stainless barrel for his conversion units, so I don't see why there should be a problem with using the LWD barrel for 460 Rowland. If it blows up in my hand then some surgeon will just have to prove why he gets paid what he does. borrowed from "concealco.com": Wikipedia excerpt: There are two key elements to the .460 Rowland concept. The first is a sharp increase in cartridge maximum pressure over the .45 ACP and .45 Super. Maximum Average Pressure is: 45 ACP (21,000 PSI), .45 ACP +P (23,000 PSI), .45 Super (28,000 PSI), .460 Rowland (40,000 PSI). The result of this pressure increase is a potential for 185-grain (12.0 g) bullets to achieve 1,500 ft/s (460 m/s) MV and 230-grain (15 g) bullets to achieve 1,340 ft/s (410 m/s). The second element, in regard to M1911 type autoloaders, is to dampen or reduce the velocity of the slide to a manageable level.
