Pop-on rear caps

Hey, my new FA 50 1.4 came, today, very nice, and all seems well.

(I was amused that it's the same kind of box they were selling Pentax stuff in the *last* time I bought a brand new lens over twenty years ago, (though that was a Canon) Still, I was like, 'Now *here* is some brand continuity.' )

Anyway, the rear cap it came with doesn't bayonet on, rather just sort of slips on there. I'm not sure that inspires all that much confidence. Are these things actually prone to coming off?

The pop off ones eventually get rough on the inside and bits of plastic fall off, usually inside the lens.

I have one pop-on rear cap, seems to be a soft plastic. It fits quite snugly. In fact it is probably less likely to come off than my bayonet caps, which do have a habit of unbayoneting themselves in my bag. But I have to say I *like* the bayonet caps better.

My FA 50 plus a couple of other lenses have had the pop'on cap. Never had any problem with them.
