I had no problems with the installation at all... I didn't use the included "tool", as it was easy enough to "rock-and-angle" the slide stop release out, and similarly install the replacment slide-stop-release-and-on-off-switch back into position. I dunno if I spent even two minutes total in the install.

If you can field strip a Glock, you got this lol.

As for usage, I find that relieving the spring tension (by **slightly** pushing the slide to the rear) facilitates the either side position of turning the laser on. (NOTE: I serendipitously found that at the particular tension I have the Tulster IWB holster I use set to, drawing the Glock moved the slide stop release enough to turn the laser on "automatically".) That [slight] slide tension relief also makes it easier in centering the slide stop release (i.e., to turn the laser off).

In case you were wondering (and why would you lol), my use case for a laser is basically dark environments (i.e. night use); adding a laser makes up for my vision impairments (astigmatism) and far sightedness (my focus on iron [night] sights can be problematic even in full light, let alone darkness). I have optical enhancement (laser & red dots) on most of my weapons. (I don't go out much at night - the laser is rarely necessary - so battery longevity isn't really an issue.)

I chose the Lasermax in particular because it can be used with my non-light bearing EDC holster of choice... it's internal, so it fits bog-standard holsters.

This was added primarily for a better grip on the 43X. I have medium size hands; I'm adapting the LH index finger push down grip to try better consistency.

The glossy black finish was a bit darker than the 43X OEM grip color. CNC manufacturing and finish was flawless. It looks good and natural on the gun, if you're into that sort of thing.

Fitment is via a compressible rubber plug sandwiched between a threaded metal "washer" on top and the recessed metal butt part of the Magwell; the screw must remain loosely attached while you force fit the rubber plug into the backstrap channel (it might help to add a drop of liquid soap to the rubber plug). There's also the slim lip/edge of the Magwell that is force fitted over the bottom edge of the grip keeping it all in place.

After getting everything in place, I gave the installed Magwell a couple of firm knocks against a wooden surface before tightening the screw. The Magwell was more than adequately locked into the grip by the compressed rubber plug.

I tested the Magwell (i.e., after installing it) with a 1/2 dozen different OEM Glock 10-round magazines with no issues at all (apparently YMMV, as I noted another reviewer saying OEM 10-rounds "didn't work")... the mag catch was solid on all of the ones I used.

The bottom of the Glock magazine stands out maybe 1/16-1/8 inch proud of the bottom of Tyrant Magwell.

This is an EDC pistol, so I was naturally concerned about printing. It's much less noticeable than a typical competition
