Good belt and holster make a difference. Carried either my XD Service 45 or my XDm9 4.5" in my CBST. All day with no issues even in the Eastern NC heat.
Lately though I've been carry my Shield Plus with factory 15 round mags but still load up with the full size depending on where I am going.

This is also what works best for me when carrying a fullsize 1911. The 1.75” wide belt works much better for handling the weight than my 1.5” belt, with the exception of Mean Gene Leather’s 1.5” belt. The problem, though, is that it may be difficult to find a good, comfortable, concealable holster that fits a 1.75” wide or thick 1.5” belt.

My favorite IWB holster is TTGunleather’s “Mike’s Special” at 3:00 to 4:30. I don’t need a 1.75” or ultra thick 1.5” belt for that combo.

For OWB, my favorite is Don Hume’s 721OT pancake holster. It’s comfortable and keeps the grip tighter to the body than any other OWB holster I’ve tried. But I prefer a wider or thicker belt to handle the weight of a heavy gun with any OWB holster. The trouble is that without filing and cutting the holster’s belt slots, it’s hard to fit that Don Hume holster even though it supposedly fits 1.75” belts. So I sacrificed a 1791 OWB pancake holster by cutting and filing its belt slots to fit my thicker Mean Gene belt. It’s just that my 1791 holster doesn’t tuck the grip in as much as the Don Hume holster.

I used to back in the day before I got much more chunky, a CZ SP01 Phantom in a High Noon Down Under IWB rig with a High Noon Rock Steady gun belt. The use of a high quality gun belt really made the difference.

I use a Tenicor Malus Sol holster for G17, X300 and RMR w/ a Wilderness belt.  I carry at 3-4:00 with a button down cover shirt.  I have the same setup on a G19.5 but I prefer the full sized grip og the G17.5

229 in a Mitch Rosen presidential holster.

The Malus Sol is an appendix carry rig. How is this actually comfortable at the 3-4:00 position? Seems counterintuitive, as there are far better options for this carry position, to include a more ergonomic draw angle.

We are BLESSED in that our every day life is so good. We may find ourselves on the way to an airport or a grocery run. Random describes us and that presents a problem for my selection of and EDC set up. Crawling on/off on a tractor is far different than getting out of the Wifes' car with my head on a swivel. One is dangerous for a far different reason than the other. My age, shorts vs. pants, activity and much more present a circumstance I've not yet found a solution for.

My personal preference for comfort is a Shield IWC but with the "stretchy shorts" I prefer even that isn't ideal.
I'd like to find a way to IWB a full size M&P 9 without gouging my side when I'm mowing or on a creeper.
Changing clothes to go from "worker" to retired guy out for dinner is a PITA with bone spurs in my shoulder.
Around the house the Shield has been very easy on my physique. At my age and size comfort is #1.
Driving so many different vehicles is also an issue.

Strangely enough I bought a shoulder rig in 2010 for a trip to Alaska that served me very well in all conditions. Hmmm.

I can carry it all day w/o issue.. its actually a much better alternative to what I had before, Bravo Concealment.

Interesting. Did you ever draw from that position? The straight angle seems like it would be awkward at the 4:00.

Yes but more at the 3, vs 4.

I’m not a large guy, 6’ 165lb, I carry a 19 with a tlr1hl and a 508t IWB with an alien gear cloak tuck pretty comfortably. Long car rides I’ll take it off but he really aside from that it’s comfortable.

I rotate between carrying a P365X with a TLR-7 Sub and a Holosun HS507K, and a PF940v2 with a TLR-2 HLG.

1. Get a good gun belt with a steel core. I like my 14oz leather steel core belt from Bigfoot Gunbelts, but there are a number of companies making leather steel core belts and some of them offer nylon (or "tactical") belts.
2. Baggy clothing. I don't need to cinch my belt as tightly because I can throw a Hawaiian shirt or plaid shirt over my black T-shirt and it'll kill whatever little bit of printing is left.
3. The body fat is your friend, and I'm not joking. I'm a fat guy and I feel like it's more comfortable to carry because I don't have a gun pressing directly against my hip bone through a thin layer of skin and fat. I got the padding there to cushion it.

Beretta 92 RDO in AIWB.  

Best enhancements are your wedges, or Dr Scholls gel shoe inserts.  Cut them to fit, and slap the Velcro on them.  Don’t be afraid to ‘stack’ your wedges either.  

Dremel for your Kydex holsters.  On the side that is against your body, you can decrease the width and footprint of the holster against you.  This slimmer profile will fit between the parts better.

Beretta 92 is very comfortable with this holster.

what belt do you have? ive had a vp9 and they arent that heavy, ive carried a Cz shadow 2 and thats a heavy mf and still it wasnt that bad. i carry right side iwb or owb in a leather holster, i currently run an all metal frame baby desert eagle in 45acp with a spare mag and that isnt that heavy either.
