I recently picked up a new 637. Let me add more info…..I can't remember how many j-frame airweight revolvers I have owned in the last 20 years or so
BUT every single one of them has had the failure of the "clear coat" . I have had 637's,638, and 642 models. They ALL failed. I still have one….bought it 21 years ago…..it is ugly,ugly, but it shoots….really shoots and I carry it in my left hand jeans pocket every day….I trust it. With my life. Now as few days ago I bought a brand new 637……let me just say it is PERFECT in just about every aspect…and the coating seems different…I cannot define how but it looks different and feels different ?..I am cautiously optimistic that it will hold up. Anyway, to end thisl long winded post, I carry the new one in my right hand jeans pocket…..two 637's …10 rounds of Remington FBI load plus p 157 grain. Soft lead semi wad cutter HP's. No reload. I am just an 86 year old , old fashioned fart!
