I recently got a 686+PC 5" that came with an extended cylinder latch . It works great! It makes the flat latch feel like your in the stone age or something. It eliminates that feeling of trying to bury your latch into your sideplate just to get the cylinder open. Honestly, I dont know why they didn't come extended already! (Maybe holsters and CC might have something to do with it. )
I've been comparing the latch that I got and zoggers above and it appears that the PC one is higher and longer. While his looks closer to the keyhole than mine does. I'm sure both have that angle that is critically needed .
I called Smith and wesson customer service and option #4 for the performance center to see if I could order more of those cylinder releases this morning- and got a big fat NO ! NOT for sale.
So I think so far, those hogue ones and the TK would probably be our best bet. And I think Amazon had them the cheapest when I did a quick search(at the time).
