Thanks for all the advice, folks. I finally settled on an El Paso Saddlery High Slide (
http://www.epsaddlery.com/pc-149-20-high-slide.aspx" onclick="window.open(this.href);return false;). MSRP is $64, but I picked it up at CTD in McKinney for $39 (they had 3 more in stock if anyone in the area is interested). A few things about this holster:
1) The gun sits higher then it did in my Kholster, but still in about the same position as my Sig P220. I'm not sure if it's IWB vs OWB, or just that my Kholster is designed for my Sig, but it's better than I anticipated.
2) This is much, much more comfortable than my Kholster. I'm pretty sure that's going to be the overall difference between IWB & OWB.
3) The gun sits closer to my side than I expected. I've got a DeSantis OWB holster for my Ruger P89 and it sticks out like a sore thumb. I guess I just wasn't expecting an OWB holster to sit this close.
4) I've been wearing it around the house for a few days now and even carried it to Synagogue this past Shabbat. All I can say is I really, really like the feel of this.
Thanks again!!!
