I have a Glock 21 Gen 4 in .45 ACP that I want to convert to shoot .460 Rowland ammunition, and I also handload.
So far, my research has found that the only difference between these two cartridges' dimensions, is that the case length of the .460 is 1/16th inch longer than the .45 ACP. This was done, to prevent higher-pressure .460 rounds from chambering in unmodified .45 ACP pistols. But, the overall length of both cartridges is the same, due to the same magazines being used for both. Therefore, bullets must be seated more deeply in the .460 and powder capacity remains the same. I also learned that a compensator must be used to delay/reduce rearward slide velocity and that a stiffer recoil spring is required.
But, if I buy a threaded .45 ACP barrel, compensator & 24# spring from Lone Wolf, can't I just handload .45 ACP cartridges to achieve .460 Rowland ballistics?
If yes, I will probably leave the compensator permanently attached to the barrel and just swap springs when I want to switch between different ammo loadings. I also plan to load only hard cast lead bullets in the high-pressure (.460 level) ammo, and only jacketed bullets in the milder (.45 ACP level) ammo, so that I can choose the correct spring.
Informed opinions & suggestions are appreciated.
Thanx, Dave.
