hey y'all this is my first post on glock talk and I have a question regarding the g23 gen 4. I was wondering if anyone knows whether the lg-619 from crimsontrace for the glock 23 is compatible with the g23g4. I talked to a girl @ crimsontrace on the phone and she really didn't sound confident in her info when she said it wasn't because of the modular backstraps. I don't use the backstraps so I wanted to know if anyone has experience with the g23g4 and lg-619 and wanted to know about the fit and accuracy. Any help would be greatly appreciated. My glock was my 21st birthday present to myself and I live in a high crime neighborhood with my elderly grandparents. Bullets have come through My windows, my house was broken into and my beagle was killed fighting off the burglars. I feel I need every advantage I can get and lasergrips are just part of my new home protection plan. Please and thankyou.
