Indeed.... as a life long fan of all things 1911A1 as a serviceman and deputy sheriff I stayed with the 45 auto in the form of the 1911A1, the SIG 220 and Glock 21 and 30. I even have a couple of the Glock 37 45GAP’s. Yet ....as the threat evolves in my arena and areas I travel I needed something in a “handgun” that would punch a vehicle body and AS1 or 2 glass reliably as well as have good stopping power with energy that stayed in the body, permanent damage versus temporary etc ......
The Glock 20 in 10mm has been filling that need and now as a civy I am experimenting with the 357SIG. I use the 1911A1’s in my IDPA competition still and consider still the 45 Auto or the new 45GAP the ultimate human control with regards to a handgun carried for personal defense.
45 and 7.62x25 are worlds apart L0L but both useful.
The latter is a good varmit round or for piercing stuff
