Back up guns? Advantages and disadvantages and philosophy?

[KHickam]

I open carry and conceal carry - I never carried a back up gun before - relying on my knife and retention to maintain my firearm in case of a grab/scuffle.

But, wondering why or why not this is a wise choice and the philosophy behind it? I carry large semi autos so with extra magazine I am packing alot of weight already - wondering if it is practical considering both my guns are heavy (M&P45 and M9) extra weight is going to be something to consider

Just wanting thoughts from those that do and the advantages of the practice as well as disadvantages.

Thanks

I think it depends on the circumstances. Some police carry BUGs because they are often exposed to danger and might need one. I certainly don't think that's the case for me, so I don't carry one. If someone is required to go to dangerous places, a BUG might make sense.

Glock 26 Primary IWB
plus
Glock 26 BUG in pocket Desantis Nemesis Holster ... both concealed, have for many years

2 is 1, 1 is none
Parts/Mags interchange, grab a BUG faster than a reload in some instances,
Also several in my Church have CHL, One was a retired LEO, but often come unarmed, they know they can borrow my spare.

No reason not to

Primary is a double-stack 1911 in .45 acp.

BUG (until yesterday when I gave it to my Daughter) Kimber Micro Carry .380 acp

I don't carry the BUG expecting to lose my primary (though that could happen), but because damage to (or failure of) my primary would leave me in a tight spot. A small, light BUG is hardly noticed even when carried all day. I just feel better knowing I have two weapons I can access. An 'insurance policy'...if you will.

Advantages and Disadvantages, probably equal out for most folks under most conditions.

Philosophy: Preparedness (must be reasonable in scope of course). I like redundancies...where my life might be at stake.
