Im looking for a new holster for my G43 once I add a red dot. Does anyone have any experience with these? I like the modularity you get. I also like that I can buy other shells and use a couple of other pistols.

Other than those, what would you suggest for a good iwb holster for that pistol?

I've been using one for my 5" 1911 for several years and now for the 4.25" Ronin. Also got a shell for the S&W Shield 45. I like it. Very adjustable and comfortable. Wish the 1911 shells came in commander length but not end of the world. I use it almost exclusively as IWB configuration so it may be overkill for me. It isn't hard to change the shells or carry modes, but you have to get the parts out and do it. If you need to carry in multiple modes through the week, you are probably better off getting 2-3 dedicated holsters, but for about $100 it is a pretty good deal I think.
