im wondering if i should go with a laser that mounts on rear site? i seen one on ebay for $124. or should i go with the laser that is in the handle? or do u think red dot is best? i still want it to fit in holster to carry. its not even had one shot thru it yet. well except for the two shells the factory gave me with the gun. i really like the glock but im kinda thinking maybe i want a S&W M&P instead?? i kinda like the looks of them better and the M&P on the barrel just sells it for me cause thats my initials lol.
