I own three drop holsters.
I like the Blackhawk Omega VI holster the best. This is my latest and the best value... read on. WARNING: Unless you are 4 Feet tall, you're gonna need the Drop Leg Extender for $10. Gives an extra much needed 5". Comes with the paratrooper strap. The leg straps are elastic and replaceable. They also are quickAlthough I bought it for the glock 19/23, it fits all 7 of my guns. With the extender, it retails for $95. However, there is a guy on eBay and sells them for CHEAP.
I bought mine for $25 delivered, and bought my extender from a local shop for $10. The seller ID is
discountblackhawk Heck, that is a $70 savings! Can't beat that!
My 2nd favorite is my oldest. The Bianchi Cobra holster with the modular leg accessory panel. Cost me $120 for the set. I actually bought a 2nd leg accessory panel so I can carry mags on the other leg. The best thing about this one, is that I can adjust it to fit the gun alone, or with a tactical light. The adjustments allow for a snug fit with either option. The only disadvantage is that the leg straps are NOT elastic. That's because the leg straps are part of the retention for accessories, but not the holster. So, I may buy some Blackhawk straps and put it on this one. I really like this Bianchi Cobra.
In last place is the Safariland ALS. It was also the most expensive @ $150 I'm a big fan of Kydex (or other molded products) so I went with this one. However, after having it for a month I felt I needed something with greater flexibility. This can only fit one specific gun. Unfortunately, I chose a holster with tactical light. If I choose not to use the tactical light, it doesn't secure the gun properly.
