GS Precision Extended Slide Lock for Glock 42

Part seems sturdy and sticks out just enough to make it much easier to release the slide when breaking the gun down.

What a huge difference! So much easier to field strip my pistol now. Was thrown for a second when I noticed that the slide lock on my 42 was held in place with coil spring instead of a leaf type shown in the videos. Super easy to switch it out. Just push down on the slide lock with your index finger. Use your thumbnail (same hand) to shove it sideways. Grab it from the other side keeping pressure on the top so you don’t lose the spring (little wiggling helps). Once it clears one side of the frame you can tip it up slightly to take the pressure off the spring and pull it completely clear of the frame. Reverse steps for new one. Took me like 30 seconds to switch it out.
