Check out Mika's Holsters. I have an IWB for my 442 and love it. In fact, I love it so much I bought one for my 6906/3414. Inexpensive and they don't look like all that much, but they are well made and he's a great guy to do business with.
A friend has a comp-tac 2 o'clock for his 642. I tried it for a while and it works great for AIWB. Once I lose some weight and the Heller commemorative 442s come out, I'm going to get one.
You get all that stuff in that little holster? I'm impressed. Reminds me of a joke about a guy that collected foreskins, but since this is a family forum, I'll leave it to your imagination.
My favorite IWB holster for the model 60 is a Jay Pee I found in a bargain barrel for $5. I think most of the leather holsters are good, but avoid those made of soft suede. The soft material allows the sharp corners of the gun to cut into your body and this soft material makes reholstering extremely difficult.
I have a Galco and it's plenty comfortable, but I have trouble getting the gun out of it fast. Does anyone have a Comp-Tac or something similar that they could bring to the shoot tomorrow that I could try?
