If you are married to using a Glock and not a traditional hammer-fired pistol, it's something worth considering. Maybe nice to have, but not a must have for everyone.
I will admit I was one of the early adopters through Indiegogo because I was interested in using it when I make the change to appendix IWB carry. Having shot about 300 rounds through my G19 I noticed:
- There's no added weight to the trigger pull (or at least I didn't notice it). I was pleasantly surprised by that.
- If you're used to holstering with your thumb-on-the back of the slide, now you'll definitely get some feedback if there's something stuck in the trigger guard.
