450 SMC in Glock 21?
Doubletap has some new loadings in 450SMC. They state this is similar to a .45 Super, and can be used in a .45ACP with a 20-22lb spring. Anyone try this ammo in a G21? If so, how's it working?
I never tried DT ammo, and I doubt that I will; however, I did try .450SMC when Triton introduced it. I used an aftermarket, threaded, compensated barrel. I just don't get too excited about dumping more powder into a .45ACP case, so have no practical use for either .45 Super or .450 SMC. I found .40 Super to be a much more interesting round.
