I used to think the Model 38/49 were the ugliest revolvers S&W ever made, and could never see a need for them. Well, after breaking my (dominant) arm, I can see where an opportunity for a precise, SA shot could present itself. I searched quite a bit for a Model 38 - I have a Model 642, but it's obviously DA only, and my Model 60 is nice, but it's no (pants) pocket pistol - and I finally found a nice Model 38 no dash on GB for just under $300.00. I'll probably carry it with standard velocity wadcutters once I've had a chance to sight in the CT Lasergrip and consider it done. I thought long and hard about the 438 and 638, but I simply don't like the lock, and I do like the older S&W revolvers.
Best of luck,
Dave
