Richard Simmons:
Some years back I purchased a 66-1 with a 2+7/16" barrel, marked "West Bend P.D.", from a retired West Bend Wisconsin LEO. I'm not a big fan of snubbies (sez the man who owns 8), but I can say this one is not painful to shoot.
I like its history and prefer to carry a 386NG or PD for the extra round, so this is as close to a safe queen as I get. I use it for training new shooters, and fun days at the range. Funny thing, methinks, like my Colt Detective Special it is popular with women.
Students often get attached to "their" guns in my classes, and I've turned down a number of "sincere" offers!
I thought I had pix of it but can't find them. It's a nice day here in October Wisconsin, I'll try to take it outside for a portrait, and post it. Although, to the OP: it isn't a 4" model.
