My nightstand gun forever has been a Glock 17 with a red dot, standard mag, and a light.
However now that I’m mainly carrying and practicing with a 365xl instead of a Glock I’m finding I’m having problems sometimes throwing the first shot or two due to the difference in grip angle whenever I switch from whatever I practiced last, to the alternate. So I put the Glock back in the main safe, and am now just switching to the 17 round macro mag on my xl, and for now am going without a light.
I actually got a jmck light bearing aiwb holster to try out having a light all the time and it’s not bad; but inertia, the desire to keep things simple, and a tiny bit more comfort have kept me without the light so far.
