I have a left handed Ragnarok Glock/X300 OWB holster on a Safariland UBL Mid-Ride base.  It's brand new, only had a pistol in it for sizing and photos.  This will take anything from a 19 through a 34 length without slide showing, a 17L would probably poke out the bottom a bit.  These are 70 for the holster and another 20 for the Safariland platform, so $90 plus shipping and backorder on the website.   I'd like to see $70 for it.   Once again, this one is LEFT HANDED. STILL AVAILABLE 

The Ragnarok is backordered from the website, everything else has a 1-5 week wait time for order fulfillment from T.Rex Arms. 

If you want me to ship, it's PP F&F and shipping is on your dime.   Reach out to me directly NEEN1zerofive45foursix4eight for you non Alist accountee people.
