I have been  using the Don Hume Jit holsters for a very long time and I have several of them for my primary weapons.  For this type of holster, you may run into some flop issues with medium to large frame guns.   The bigger the gun the more likely you will want to have a larger full coverage holster.   IWB can be a uncomfortable carry method but it truely is the most appropriate.    Using locking devices or paddle holsters can cause snagging, make it harder to conceal.   The nice thing about Don Hume holsters is they are very reasonable priced and for $20 or so you can get a very good holster.

I compared these two holsters with a Sig 228 and a Glock 19,  most of this is preference, but it seems that when I used the Desantis holsters for the Sig 228 did not flop around as much as the Don Hume Jit.   There is about an 8 ounce difference between these firearms even though the sizes were close to the same size.   This definitely gives Glock and edge on the weight, but much of this is about how well you handle and shoot a firearm because it’s not about looks its about proficiency.    The Desantis Speed Scabbard is more money but I think it’s a nicer looking holster too.
