I went to the range today with my 629 (along with my 627 Pro and Beretta 92) and my chronograph, so I can give you some concrete numbers for you to look at:

Pistol - 629-3 Classic, 6 1/2" barrel
Bullet - Bayou Bullets coated 240 grain SWC
Primer - CCI 350 (all I had on hand)
Case - FC
Powder - 7.1 grains Unique
Average fps - 871
ES - 64
SD - 17
Power factor Avg - 209

These were real pleasant to shoot and shot accurately. Felt recoil was less than the 357 rounds I was shooting today, which were 158 grain Zero JHP loaded with 14.5 grains of Alliant 2400. I'm sure part of that was due to having the full lug 6 1/2" barrel as compared to the 4" flat sided barrel of my 627 Pro, but that load should shoot pretty softly in just about any length barrel 29 or 629.
