My daily carry is a G19 in an Alien Gear IWB but I am looking for a thinner version, a single stack. Finding a place that has both a 43X and a 48 in stock for side-by-side comparison is about impossible so I thought I look for opinions here. I am planning on the 48 but a friend suggested I look at the 43X.

I plan to carry AIWB or maybe at 4 o'clock. Not interested in other brands at this time because I get Glock Blue Label pricing, although I will probably end up with a Sig 365 at some point.

Thoughts or experience?
