for S & W 3913 Leather or nylon?
Thanks for your help

I'd go leather, properly molded to the specific firearm for good retention and trigger coverage.

Take a look at Ritchie Leather or Alessi Holsters.

Or, if you want to look at nylon, look at a DeSantis Apache. Lined with
sheepskin. Very comfy.

Alessi or Kramer (Galco for a decent and more affordable option).

the OldSchool Alessi ankle holster (made during the lifetime of the late Lou Alessi) has long been the gold standard by which ankle holsters are measured. Lou Alessi made an ankle holster that actually made carrying a handgun at the ankle a comfortable experience, and that borders on magic. most of the Alessi ankle holsters that i have seen for sale are examples from the online auction circuit (ebay/Gunbroker), and most of these were made for the S&W J-frame. it may be difficult to find one for your pistol. nevertheless, the old Alessi is as good as it gets and if you can find one it will be well worth any amount of money to own it.

Ritchie Leather Co. Inc. is an active gunleather maker and may be a good option for a new ankle holster. Skip Ritchie learned from, worked with and became a business partner to Lou Alessi. it's very possible that an older Alessi holster you might purchase or already own was made by the hands of Skip Ritchie.
