Maybe you should've used handloads.Not a Glock. Glocks are much more boxy. It's a SIG P220, chambered in .45 ACP.Legion ModelLooks really close to the legion model, too. Just came out. Too exppensive for my tastes, though. Going for a Savage 110 Tactical in .308 Win and putting a 30" threaded on it.It's .45 ACP because the shell is shorter than a 10mm and wider than a 9mm while still packing a punch when impacting or entering a target.
