@Styx wanted a report and I'm sure everyone else would like to hear how things went. I put about 100 rds of 9 and 50 of .38/.357 thru it today.
First, I started with 9 without using the moon clips as after my troubles with the J frame 905 without using clips I wanted to see if the larger frame had the same problems and it does not; you can shoot the 9mm without clips in the 692 without any problems.
The only issue I had was an occasional light strike with 9mm, but that could have been the ammo (Flinchtester Plight Box) or me not pushing the round into the chamber deep enough. I only shot with the moon clip one cylinder full, no issues, but I'd have to shoot more with the clips and with different ammo to know for sure.
No issues with shooting .38 and these were all handloads of mine. Trail Boss loads felt like shooting .22, standard .38 felt like shooting .32, plus P felt like regular .38, and .357 felt like .327 does. The 692 is the largest, heaviest .357 I've ever owned and shot and the weight plus the porting really cuts down on muzzle flip and felt recoil and reminded me of why I don't care for .327 in L sized or GP100 size frames and it's because the benefits of recoil reduction of the smaller caliber reach a point of diminishing returns.
Biggest challenge I had all day was getting the rear sight dialed in as I had to raise the rear almost to its max as Taurus had the thing cranked all the way down out of box. I was missing so much that I was starting to get mad, but the last adjustment I decided I'd had enough and backed the screw out a ton.
Didn't notice a POA shift between .38 and 9mm, but I also wasn't shooting paper. I'm thinking I'll put this on paper in the next few weeks, but I'd really like to get some 124 and 147 gr 9mm in first to see if it prefers a certain weight for 9mm.
Bottom line: This is the most expensive Taurus I've ever bought, the biggest .357 I've ever owned and the more time I get with it, the better I get. I like it more than the 905 and would recommend the 692 to anyone looking for a high value revolver that's cheap to shoot, but effective. I can't speak to the shorter barrel versions, but I presume they'll be as good as the long barrel.
