I've known people whose pocket revolver cylinders have bound due to lint or thread
I find this claim extremely unlikely.
When I switched from carrying a semi-auto to a snubby revolver more than a decade and a half ago, I have carried virtually every day...for the better part of the day. My S&W M36, and later my Colt DS, is usually carried in the pocket and after a week or so gets quite covered in a significant amount pocket lint debris...even the occasional errant thread. Lint accumlates despite my snubby being oil free and dry as a bone. More than anything else, I would be more worried about coins, gun wrappers or keys getting stuck or jammed bewteen the cylinder and frame. But I dont carry such things in the same pocket as my snubby.
Since 2001, with the exception of deployments, I shoot every week a local range as a paid range member. I always shoot my carry gun and I always shoot what I load for carry. Long, long ago I quit cleaning before range time. And with hand on heart I can say that I have never experienced a single stoppage or bobble from either the Smith or the Colt. Ever.
I have never heard of or read a documented revolver stoppage caused by pocket lint.
Interestingly enough, I have personally observed during my range time many subcompact carry pistols such as Keltec's, Rugers LCPs, PPKs, Kahrs and even Glocks all experience some kind of stoppage. I am fairly well aquainted with most the shooters that frequent my range, but even if it is a stranger who is having problems, and I am close enough to his/her lane, I will usually inquire about the particular ammo they were using when the stoppage occured. 9 times out of 10 the stoppage occured not with "range ammo"... but usually their "carry ammo". And usually it happens within the first magazine worth.
