As-promised:
This is the Propper I wrote about in my post above -
https://www.propper.com/bags/propperr-range-bag.html , which appears to be identical to the Reebow listed in the OP.
Sorry about the messy backgroud. Our basement flooded last summer, and we're still in the process of the interior reno/consolidation.
^ Outside of the bag, main front pocket on the left (wide side). To the right is a webbing panel, on which I typically lace through the trauma bag (Dark Angel DARK Slim -
https://darkangelmedical.com/d-a-r-k-slim-trauma-kit/), when my daughter goes to the range with me (this is her dedicated pistol range bag). The main pocket has two (very nice) pulls and a VELCRO ID-panel at the top.
Inside that long pocket we find:
A six-mag bay (those are Magpul PMag GL17s, standard 15-round Glock 17 mags, so you now have an idea of size/overhead), and a zippered mesh pocket.
The bag has an orange lining throughout, which I find to be very nice as it helps offset dropped small, dark parts very well.
I've opened and laid out atop the bag the cleaning pad that's included in the bag. It's just slightly bigger than the bag itself.
On the other wide side of the bag:
Zippered compartment on the main bag side (versus the drop-down side, on the other side of the bag). My daughter likes to put her earpro and eyepro (in the black case with orange triangle symbol) in this pocket. It's nice that you can zipper it, to retain valuables. She's got spare batteries and her earplugs in there, too. Those are standard-sized muffs (ProEar Golds, the equivalent of today's "SC Tac" model) for-scale, and yes, everything fits inside and can be fully zipped with minimal fuss.
You can also see in this picture above how the DARK Slim laces into the webbing on that side of the bag.
^ This picture shows this pocket closed. Zippers just have 550-cord pulls, not the nice rubberized pulls on the main long pocket opposite to it.
There's a couple of open pockets on the outside. That's a ballcap in one (which provides scale), and a pair of sports "compression sleeves" in the other (she's a kid, so she really doesn't like burns from spent cases: if she wears a short-sleeve shirt to the range, she'll slip the sleeves over her arms).
My fat left hand is holding open a rather reasonably sized pocket on the narrow side of the bag (opposite side is, remember, the webbing side). It has a partial-length (although more than reasonable coverage - I actually wouldn't hesitate to put, say, earpros or a med-kit in there; it's certainly large enough for a couple of bottles of water) VELCRO closure.
You can also get an idea of the main shoulder-strap hardware and setup in this picture.
Finally -
This is the inside of the bag. The interior on both long sides is covered by pile/loop VELCRO, while any area not is again high-vis lined in that same orange. You'll see in the upper right corner a hint of some webbing - that's actually a separate VELCRO(hook)-backed panel (I forgot to photograph this, I apologize) which allows you to mount additional gear, and it can mount, for example, on that long side where she's got her PPEs, which is covered in pile/loop VELCRO. The pile/loop lined interior of this main portion allows the ancorage of up to two divider inserts, which are also in the same hi-vis orange color as the rest of the liner (again, I apologize for having forgotten to show this feature), should you decide to subdivide this main compartment.
Instead of showing the inside empty, that's a stuffed-to-the-gills Midway USA Tactical Pistol Case -
https://www.midwayusa.com/product/939160870 . If you go to that product page, you'll see that this particular case has two zippered pop-up pockets on the back, along with a 7-bay mag-pouch on the front. In my picture, all of these pockets are filled, with the back pop-up pockets each carrying about 100 to 150 rounds of .357-SIG and 9x19 ammo. My daughter's G17 is laid on top of the bags for scale. The main compartment of the Midway USA Tactical Pistol Case itself can hold two G17-sized handguns in an L+inverted-L/stacked format.
The two zippers on this flap also have those nice rubberized pulls overlaying cordage.
A final clarification is that the two long side pouches both protrude away from the main compartment, so main compartment volume is not impacted by what you fill those two side pouches with.
Hope this helps!
Maybe provide the number of the state Better Business Bureau.
