I usually wear a Glock 43 with a Crimson Trace laser/light combo, with two seven round mags in reserve.
I have been trying out an iron sighted SIG 365 XL.
I tried it with the red dot, but can’t get used to it.
It fits in all of my Glock 43 holsters, as does a Ruger SR22.
I run the 12 round mag in the gun with a 15 as a reload in my key pocket of my jeans.
So far so good.
The trigger reset is a bit different than the Glock, and that’s taking some getting used to.
