HI everyone. About 10 years ago I got out of shooting and sold all of my firearms. I'm now getting back into them and am looking to purchase a Glock 19. I've never owned a Glock before, though I have shot them before, and would like your input. If I were to purchase an accessory or two for it what would you suggest? Slide stop, night sights, mag release extension, etc. Thanks in advance for your input
