I'm closing in on my IWB carry rig for my G43 with +2 extension...the Tulster holster came in today, along with a new Uncle Mikes velcro closing inner belt... the belt is easy to adjust length due to the velcro, thick and stiff to hold the belt clip securely, and with suspenders (Perry J clip model) easily supports the weight of the small G43 and cell phone on the same side...
the Tulster has a larger body shield than the DeSantis Slim Tuk and is easier to re holster the pistol.. I use a cotton Columbia fishing shirt for a cover up... so far it has been working out well
I may still carry in the cargo pocket of the nylon shorts, but it is considerably slower, and I think I can get away with a short sleeved Columbia shirt for a cover up without heat exhaustion
