For anyone who may be looking to get a sight pusher tool I thought thought I would share my .02 here. I bought a used Glock 26 and the previous owner obviously had a low left issue because the sights were pushed clear to the side of the slide. I had previously looked at the MGW sight pusher tool which is the standard but by the time I bought inserts for the G43 (I have the 17, 19, 26, and 43... just missing the 34 and 17L:) it would have ended up being more expensive than the Real Avid universal tool. I don't really envision using it on anything but a Glock, but then again I do have friends... and they also have guns.
Overall impression is really positive. This is a very solid piece, very heavy, and well machined. I think the fit and finish is great and everything slides smoothly with no slop. I initially didn't set the pusher inline with the sight but on subsequent attempts I figured it out, tiny little rub mark on my rear sight which was solely me not putting it in the right place, probably would recommend a piece of blue tape if you are worried, I am not. Again this was on me and it is a microscopic mark.
The really thought this through and it is a very well designed piece. I know at the end of the day this is just a sight pusher, but it is a $150 investment so I just thought I would share. If anyone has any questions or would like pictures let me know.
As a bonus, for those of you who read the directions, on the back of the literature there is a message regarding their philosophy on life and business to their "Friends and Customers" that is worth the read.
