Just received mine this morning, looks to be very well built. I had the alien gear owb and it didnt have any type of extended backing to help with guiding your pistol back into the holster. This vedder holster does have that which is a plus.I'd like to know about these as well. I follow them on IG and a few gun guys I follow suggest them. But that could be paid advertisement so who knows.
Sig p239. 40Looks good. What ya carry?
FWIW, ya might want to check it IRL, as in, wear it a few days. I have bought a couple (not the Vedder mind ya) high dollar, ie X-breed etc.... holsters like this for my High-Power and 1911s that when used as I normally daily carry had the issue of "pressing" the mag release button and in the case of my old HP is "not" a good thing (mag-disconnect... bad). In the 1911s, while no mag-disconnect issue the mag would pop-out hitting the floor or be found in the seat of the truck.......
I have a couple Vedder IWBs, but don't care for them much, save for modifying 'em or using them for spare parts for other brands.
My fav, IWB and OWB holsters are/were made by Frank Procter's WOTG company, (appears the IWBs are no longer listed).
