Havent had a chance to shoot it yet. Does the cut out in the mag well mess with you any? I notice it when dry firing, but not sure I would pay much attention when actually shooting... kinda like the finger grooves on previous gens.
The cutouts for magazine extraction on the Gen 5 will be far less objectionable if you ever need them to get the magazine out after a malfunction (never with Glocks I know haha). I’ve never noticed them while shooting.
