I realized I have 3 types of 'operating systems' on the guns I own, and I will try to stick to them for the serious firearms
For long rifles, the charging handled is pull straight back, the safety is ahead of the trigger and you push it forward to fire. These include the M1, M1A and Model 11 shotgun from Remington.
For pistols there is load and go. DA only. Revolvers and the Sig fall into this group. I could get more revolvers, or the Glock/M&P/XD route.
The other is a frame mounted safety, down to go, on a SA pistol. This is the 1911. I'll eschew from getting some other safety system like on the slide, or switch 'up' to go. Or anything with a decocker like other Sigs, Berreta. or various other models. Keep it simple, like my ammo inventory.
