Interesting idea.  Lets people practice dry firing without having to rack the slide every time to reset the trigger:

This guy doesn’t like it much.  He talks about how it’s not identical to an actual trigger pull:

$99 on their website.  Seems kind of $teep to me.  I’m really surprised that someone (or Glock) hasn’t been able to develop some drop in solution that exactly mimics the stock trigger.  I’m not a huge fan of dry-fire-then-slide-racking, but I’m also not a fan of not having the exact same trigger pull… more because I’d be annoyed more than anything else.  I’m aware you can get “trigger reset kits”, but those aren’t exactly a easy fix because they require swapping of parts.

Thoughts?
