  • Which firearm did you use with our holster? Glock model 30sf

Great holster Quality is top shelf

This is the 4th one I had purchased. I just love this holster once broke in there the most comfortable I have found. Have a box full of others that don't even come close. My only grip is that the size 4 it's a tad small for the Glock model 30sf but the size 5 is a tad large. So unfortunately, it's just gun is in the middle. So, I stuck with the size 4 as recommended when molding I finally got it to fit but it was tight. I would have liked a little more coverage for the slide and rear sight as the other ones I have for other guns. But it still works quite well so I shouldn't be griping just if you're planning to use this for the model 30sf expect it. Still so happy to have read the article in G&A and took the gamble (is twice the price of most out there) just wish I would have read the article before I started to waste money and all the others.

  • Which firearm did you use with our holster? Sig Sauer P365X Macro


I read the instructions and watched the Video, I followed it to a tee. Well let me say I love it. Holds well and draws perfect. I have to say it’s a custom holster! No other way to describe it. Look no further.

Look no further! This is the one.

If you need to find a holster for most firearms, one of their sizes is bound to fit. Basically, with this holster close enough is great. No more waiting for the market to make a fitted, comfortable holster with excellent retention to fit a new firearm. Especially for us LEFTIES! Ordered directly from 1719, and the product arrived quickly. Really nice packaging, and excellent directions. After "cooking" the holster and forming it around my pistol according to instructions, it has retention as good as kydex or a custom leather holster. In fact, I thought I overdid it a little with the provided tool - the first time I tried to draw, I pretty much gave myself a ******! No worries though. After a few wearings, it loosened up just perfectly and the draw/retention is perfect. Plus, I can always recook it and start over if needed. As far as comfort, this is as good as it gets. Again, the retention of kydex with the comfort of an all-leather holster. I've worn it all day from appendix to small-of-back very comfortably. 9:00 was the exception as I can't comfortably conceal anything over my pointy, bony hips. Concealment is fantastic as well. Most subcompacts or micros should just disappear, and if formed right, leave just the right amount of grip exposed for a good draw. The grip is tight to my body at all positions, but at 10:00 with a slight forward cant, it just disappears. With the provided rubber grommet between the holster and either 1.5" or 1.75" belt clips, you can easily tuck your shirt in. Getting the OWB model for my CZ 75B, as there's no need to look elsewhere for that.
