I’m currently running 185 gr Black Hills with Barnes bullets, but it’s got nothing to do with magazine weight and it’s not in a 1911. It’s a way of dealing with California’s non lead ammo regs. My USP full size always has non lead, and when I go into big critter country the hollow points get swapped out for hand loads with 200 gr Cutting Edge solids.
The 185 gr Barnes is on Doc’s list but if I had a heavier non lead option I’d use it. And if I knew I wasn’t going to be off the pavement for a while, I’d go back to a heavier conventional option. The non lead is for my woods gun only, and is a way of not being able to forget and need to waste time explaining to some rookie ranger that it’s not being used for hunting.
Those 200 gr SWC are sweet for practice though.
