For the sake of it, I am going to stick to what would be a reasonable budget.
1. Sig P365 9 mm.
2. Ruger gp100 357 mag
3 Super redhawk 44 mag
4. A 1911 in the 1911 chambering(ya. 45 auto)
5. A 22 revolver that would allow 22 mag as well.
I have stuck with what I would consider practical at this point in life. There are several of the above, that I could easily trade out for a classic Smith & Wesson, or a custom of some kind. Also, if it doesn’t bend the rules, I could also throw a Sig 320 FCU in there, and have a stack of barrels, slides and modules for it…
