What's the best way to get Unhindering Shield for my Magus?

[Bob Genghis]

I really want to get Unhindering Shield for my magus that just turned level 11. The other melee members of the party are an invulnerable rager unchained barbarian, and a rogue/swashbuckler.

I feel like my character is a bit of a glass cannon, and Unhindering Shield would really shore up my AC. I'm a STR/Int magus, with 14 dex.

Here are my feats:
Blind-Fight (from a Wayfinder w/ Incandescent Blue Sphere)
Rime Spell
Combat Expertise
Moonlight Stalker
Outflank (unconventional I guess, but the barb and rogue both have this)
Craft Wondrous Item
Improved Familiar (a Dust Mephit)
Intensified Spell
and one more feat in the air, possibly Dimensional Agility or Craft Magic Weapons & Armor

What would be the best way for me to get Unhindering Shield?

I could spend 3 feats on shield proficiency, Shield Focus, and Unhindering Shield, possibly sacrificing the moonlight stalker chain to do so (including Improved Familiar, which I only had to get Blur cast on me)

Taking a level in fighter, and adding a Sash of the War Champion would give me both shield proficiency, and Armor Training to avoid having to spend a feat on Shield Focus. And of course the bonus feat. I could still sacrifice the moonlight stalker chain here, and just use it for other goodies.

I know everyone says losing a caster level is never worth it, but I think I could use the AC boost. I only have so many actions to cast defensive buffs and still contribute to offense.

edit- I am a hexcrafter. I had considered the Myrmidarch, but I'd rather not lose my existing archetype. Not 100% on this though.

As shields can be enchanted as weapons, Training for the last feat would be helpful, at least.

Wow, I did not know that, thank you! Can even a buckler be a weapon?

There is a style feat that allows you to attack with bucklers.

Not worth it for a magus; you cannot combine Spell Combat with TWF.

[Bob Genghis]

Do you need that feat though in order to enchant your buckler as a weapon, or is the existence of it enough to enchant one?

[Cavall]

Buckler can't be used to bash without special ways around it. Therefore, no.

Nothing in RAW exempts bucklers from being enchanted as weapons.

A shield could be built that also acted as a magic weapon, but the cost of the enhancement bonus on attack rolls would need to be added into the cost of the shield and its enhancement bonus to AC.

You just can't take advantage of that enchantment without Upsetting Shield Style.

There are a handful of weapon enhancements that are usable on bucklers, even for people who cannot attack with them. E.g. called, impervious, and glamoured.

A buckler may also be used as an improvised weapon by anyone, allowing any weapon enchantment to function normally.
