They make one that goes in place on the guide rod.
Does anybody else not like the how the glock ctc makes the grip feel? I tried to get used to it, but sold it. I know lasers are beneficial in some circumstances but I shoot better without 'em on my Glock.
I also took 'em off my Glocks, for similar reasons. They increased trigger reach and grip circumference, changed the grip angle, and banged the base joint of my thumb in weak-hand fire. Lots of the CTC products are great, but the Glock unit isn't great for me.
I'm not sure I need a laser, anyway.
Not a big fan of lasers.Agood bright lite,night sites,I'm a happy camper.
