For my Glocks, I'm using
http://www.akerleather.com/off-duty-holsters.php?cat=off-duty-xr&name=FlatSider+XR+Series+Holsters
It's just like the Galco Fletch, same "forward" design where the outside of the holster has all of the molding for the gun, while the body side is flat. If you read Galco's description on the Fletch, it explains it all. The Aker is a mid-ride, not a high-ride and is less expensive while being very well made. The Galco Fletch rode so high that I had a hard time drawing from it. It might be great for someone 6', but I'm only 5'9".

I prefer closed bottom holsters, but with the "slide" style, I can carry my full size, compact or sub compact in the same holster. I have one of these for my P99. Now that I sold my P99c, I could have a closed bottom holster, but I bought the holster when I had both.
Last, but not least, for my Sig, which I just recently got and finally got to the range yesterday, so I haven't carried it yet, I have a Bianchi 82

I don't have any real experience with it yet, but I know many that do and it's a well liked holster. Very secure, while still easy to draw from.
I
never buy from the manufacturer's website. Opticsplanet.com is good for Bianchi. For DeSantis, I use their website to find the model number of the holster I want and then I Google that part number. Generally, I can find the holster for $45-50 instead of the $75-85 MSRP. The Akers I just Google.
eBay is also a great source for good prices, but you have to really narrow down what you're looking for. I've gotten some great leather holsters on eBay, including some lesser known brands that are still great holsters.
