Glock 21 Converted to 460 Rowland


Perhaps one day I will slow long enough to take photos of the gun I am reviewing. Since this little article is geared more to solid communication than photo journalism, I’ll simply paste in an Internet photo of a Glock 21 in 460 Rowland and be done with it. It could be that the reason so many folks visit the pages of Hickok45 on YouTube is that he is just straightforward and simple.  To me, a wonderful thing. 

The photo looks almost exactly like my 460 except I have a little more space between compensator and slide as I went for a 6.61 inch Lone Wolf barrel.  I chose a Fire Dragon 7075 Aluminum compensator threaded for 0.578X28 right hand threads on the Lone Wolf.  I chose this compensator because it can be locked with set screws.  More on this after I fire the Rowland for considerably more rounds than have been through the weapon now.  I did not Loctite the set screws because I want to be able to remove the barrel from the slide for cleaning.  We’ll see how well the threads on the end of the barrel hold up.  If I’m not happy with the compensated barrel I will move to a ported barrel. 

Now, what is this thing?  I’d call the 460 Rowland an improvement of the tried and true 45 ACP.  It begins with a case that is 1/16″ longer than the 45 ACP case, actually closer to a .451 Detonics case in the webbing and primer area, that seats the normal 45 ACP rounds deeper to achieve the same overall length as the 45 ACP round.  With all this is place, the 460 Rowland is rated at 40,000 psi versus 23,000 psi for the 45 ACP +P. 

In order to get the gun to function I also added a 24 lb. recoil spring riding a steel rod and used magazine springs from  The reason for the increased magazine spring rates, which I can certainly attest to when trying to load the magazines, is said to eliminate the “limp wristing effect” so often seen with the 45 ACP for some reason.  I suspect the physics of the old 45 ACP case are such that most magazine springs simply do not provide enough upward momentum when the slide clears the path for another round to be loaded.  It is physics more so than shooter.  Just my opinion. 

Having said that I assure you that if you are in need of stopping a charging African moose — which seem to be very common of late – you are not going to need six hits.  A slightly to the right of chest centerline is going to bring any attacker to a screeching halt.  The 185 grain Gold Dots are most wicked.  They fragment when hitting almost anything I’ve shot at from soft lumber to gelatin to water jugs.  At some 1500 fps the old Gold Dot will definitely do the job but it is going to fly apart and scatter throughout any man or animal desiring to take you out. 

I’ll add range photos as I get back around to it.
