What do you consider a full size gun.? I have a Glock 19 Gen 3. Does this meet your full size gun definition?

No, the Glock 19 is considered a compact. The equivalent laser for your gun is the Crimson Trace LG-639G.

is the grip thicker because of the 4 batteries? also, does anyone know how it fits the G31 gen4 .357 sig?

No. It actually fits my hands better...just reall hard to get one side of the grip pin to align. Grn is BRIGHT!

Does this fit glock 45?

No - .45 ACP Yes - .45 GAP (model G37 only)

Does it fit a Glock 17 Gen4?

Yes it will fit the gen 4 glock 17. Hope this helps. Thank you for your interest!!
