I have found that for outdoor purposes, I much prefer flap holsters. They are designed to tiny bits of trash from finding their way into your gun. They save a lot of cleaning and generally protect the gun more. The challenge is to find flap holsters. Uncle Mike used to make them. I think Galco and Mitch Rosen have also made them. The variant of Bianchi's military holster is only one currently mfgd. of which I am aware.

I also prefer holsters of Cordura Nylon for outdoor use. They can take a lot of abuse without showing it.

I have happily used Bianchi's current thumb break holster of cordura nylon in both belt loop and paddle attachments. Both have their pros and cons.

These comments apply only to belt/waistband holsters. I still haven't gotten around to trying the other modes of carry.

Good luck,

John
