Jim Burke is somewhat famous in the North Texas area for making fine leather holsters. This is one that I bought from him at a gun show and never really used because the cant is too extreme for my tastes. It works excellent at about the 4 o'clock to five o'clock position, but I do not wear my gun that far back. From what I understand, Mr. Burke has passed away and these holsters are no longer available. This holster is designed to fit any Glock 9mm, .40 cal or .357 Sig handgun. It has a "17" stamped on the back, which I assume refers to a Glock 17. Either way, it will work for any of the calibers listed above. I should note that it is somewhat loose when not on a belt. Always has been. But, once you tighten the belt then it snugs up nicely and will securely hold your Glock. I believe I paid in the neighborhood of $60 for it. It is slightly worn so I will sell it for $35 (OBO) including shipping in the U.S. I will take Paypal, check or money order, but if you pay with a check I will wait for it to clear before I ship the holster. First come first serve.
