I have been doing my research about different laser options for my G 19, and have narrowed down to the new Veridian Green laser light combo, or the new Crimson trace 417. One advantage of the Crimson is that it seems it would hold a better zero, as the rail section of the frame flexes alot during firing ( it also gradually gets a worse pignose hate that). One advantage of the veridian is the more visible laser being green. I would like to gather from anyone on GT with rail mounted laser: Does the unit hold a zero well? Also, Does the pignose on a Glock put the laser out of the adjustable range of the laser? These may seem like stupid questions, but I would hate to buy a 300 dollar veridian and find that I cant get it zeroed because of the dirty little piggy nose sticking all way up like. Also, opinions on alternative lasers, or any other insight into laser options is welcome. Thanks!
