Ways to gain extra feats

[Shinoskay]

So, this is less a question and more a guide of sorts. However, I am extending it to the question realm in that I expect I dont have the full answer.

Several times now I have searched up ways to gain feats from items, 3.5 comes up a lot but the best I've gotten for pathfinder is 'ioun stones and wayfinders'.

That's cool, but after years (on and off again) of searching I have finally started to really have a grasp of what all items give feats and so felt it was time to start putting them into a proper list.

Why this is in the rules question?
"Did I miss anything?" is a solid application here.

Starting off with the best option of all: Training
- Training weapon ability
grants one combat feat to the wielder as long as the weapon is drawn and in hand.
The feat is chosen when this special ability is placed on the weapon. That feat cannot be used as a prerequisite for any other feats and functions for the wielder only if she meets its prerequisites.

- Gloves of Unexpected Violence

normal - Catch off guard feat

Greater - improved improvised weapon feat

- Shieldmarshal's Pistol
grit deed feat, pick one:
Deft Shootist DeedUC, Fabulist (Pathfinder Player Companion: Champions of Balance 19), Gun Twirling (Champions of Balance 19), Leaping Shot DeedUC, No NameUC, and Ricochet Shot DeedUC

-Helmet of the Golden General
grants its wielder three performance or teamwork feats.

- Ring of Tactical Precision
By wearing the ring for 1 hour, a creature may imbue it with a teamwork feat he knows for 24 hours. During this time, any creature wearing the ring may use that feat when cooperating with the creature that imbued it, but not with other creatures even if they possess the same teamwork feat.

- Perfectionist Shavtoosh
If wrapped around at least one limb, it grants the wearer the Improved Unarmed Strike feat.

More coming soon, I'm lazy so I will be editing them in. Feel free to post whatever is not on the list already though, maybe I havent actually found that item yet.

[Scott Wilhelm]

Inquisitors, Brawlers and Free Style Fighters can swap out Feats they know for others that fit the occasion.

MOMS Monks get a Wildcard Feat.

The Human Feat Martial Versatility lets you apply any weapon-specific Feat to lots of different weapons.

[avr]

Items Scott. Mentioned in the OP if not the title.

[Shinoskay]

I should have put it in the title, my bad.

Perhaps boldening it in the first post will help.

*edit
actually, it wont let me edit the first post. damn, nevermind.

[avr]

Merciful vambraces
- as extra mercy feat 1/day

Seeking and veering ranged weapons
- more or less as improved precise shot, seeking for concealment and veering for cover

Migrus locker, periapt of temporary familiar
- familiar bond

[Lady Asharah]

Agile enchantment on Finessable weapons
- Fencing Grace/Slashing grace without any of the feats caveats. Hell you can even put it on finessable two handed weapons (but no extra bonus for wielding it two handed) like Elven Curve Blade or Estoc.

I really wish I knew about this enchantment at the start of the game I'm currently in.

[blahpers]

Gain experience levels.

[Alphavoltario]

Blind Zeal Religion Trait [Vildeis] gives Blind Fight as a bonus feat. Also limits what you take a negative to for being blind.

Know it's not an item, but a feat in a trait slot isn't terrible.

[Shinoskay]

Shawl of the Lingering Phantom
- Skill Focus feat in both skills determined by her phantom’s emotional focus while the phantom is manifested in ectoplasmic or incorporeal form.
(so 2 skill focus feats)
