I just compared the 3" 686P, SKU #164300 & MSRP $849, with what I chose - the 8-shot 2 5/8" PC627 UDR, SKU #170133 & MSRP $1,049. Sure, the out of pocket expense is ~$150 street price more. You do get an N-frame Performance Center product, with several refinements; enhanced trigger, moonclip ready, eased charge holes for faster reloads, ball-detent lockup, etc - and only .8 oz heavier than the L-frame 3" 686P.
I liked my first one so much last April that I sold an old friend to purchase a second one last October. Below is one of my 2 5/8" PC627 UDRs and my 4" 627 Pro, for barrel length comparison. Also shown is an 8-shot moonclip and a 5starfirearms.com speedloader and 2x8 loading baseplate. The ammo shown is the Remington R38S12 variant of the .38 Spcl +P 158gr LHPSWC, my self-defender choice.
I am expecting my Lobo Leather OWB holster any day now for the 2 5/8" PC627 UDR, so it could be a carry gun if needed. My latest choice has been either my 642, a 15.5 oz Airweight 5-shot .38 hammerless J-frame, or it's older/larger sibling, my 296, a 19 oz AirLite-Ti 5-shot .44 Spcl hammerless L-frame. Both are carried in their own Mika pocket holster. I know, especially during day hikes, I am much more apt to be found with one of the liteweights in my pocket than anything on my hip - where legal, of course. I just thought I'd suggest an alternative.

PS The UDR's sights are so easily picked up, I actually shoot it more rapidly in Steel Plate Challenge than I do the 627 Pro! Both guns have aftermarket grips.
