Hello and welcome Nikia,
That holster looks good. The past few days I've been thinking a leather pocket holster. I was looking at a Taqua PK5-020. It looks like thin leather and with a flap. I tried making one and liked it but for reason. the was not easy to get my fingers in the pocket to draw. After a while it formed to match the outline of the gun grip and I had a hard time getting my fingers in there. I had to pull back the flap and then get my fingers in. I think though if the flap was a little taller above the gun grip (stick out of the pocket more) it would be better. If you look in the Gallery in the black bar menu at top of window and click then click on holsters you will see a homemade one. This is what I talking about. I eventually took the flap away and added some length and reinforced the edge with another thickess. The lower edge of the thickness rests and acts a stop against the pocket. It works glory be. I eventually kept cutting down slide retainer to what is shown now so my fingers/thumb could get hold of the grip easily. I didn't like the idea of the trigger being exposed but the thumb is the only thing going in the pocket and it wouldn't pull the trigger. Since then I bought and now have several De Santis Nemesis holster which I really like.
Almost all of the leather holsters I've bought I wrapped tightly in two plastic grocery bags the gun, with emphasis of wrapping more at the slide to holster contact area, in forced into the holster and let sit for several days and night. It loosens up the fit pretty good.
I seen referenced the word "boning" instead of "molding" in several holster links by the way. I only write this as I'm looking for correct terminology and you seem to have some leather experience.
NOTE:
Rule 14 doesn't read that you can't refer to an item of interest. Just that it can't be a "for sale,etc" item AND linked here. I see no harm in copying and paste-ing an item of interest, with it's name to talk about. There is talk of different guns and or items with pics often here which is not the same as linking to a for sale item. Heck, everything is for sale. I may have to take back my words but I don't read the rule as prohibiting conversation of an item.
14. List ALL 'FOR SALE' items in the proper 'WTB/WTS/WTT' forum. You are NOT to list items for sale in any other part of the site. Find the proper category for your item and list it there. DO NOT use other forums to sell anything. This also pertains to items you seek that are 'Wanted to Buy'. Put these in the 'Wanted to Buy' forum in the Want Ads area ONLY. Also, DO NOT post a 'link' to 'For Sale' ads you may have on other boards, such as GunBroker or GunsAmerica. Links in other forums hold the same weight as Ads themselves, they aren't allowed.
