does it fit the Glock 19x?

Yes the UCH17 will fit the Glock 19X.

I just purchased this for a Glock 45 MOS with an installed red dot. The top piece will not fit due to the lip along the top edge. Suggestions? I didn;t see anything about these not working with red dots.

It depends on the red dot. If the red dot overlaps the area covered by the charging handle, obviously that is an issue. You may be able to make it work by sanding down/dremeling the charging handle a bit. If you'd rather just return it for a refund, please request an RMA here.

Do these hamdles work with the trijcon HD sights?

I believe so but can't be certain. Feel free to try and return if not (as per our money back guarantee)

What type of charging handle would you recommend for a zevtech citadel long slide

Our charging handles are created for specific compatibility with the brands listed (like Glock). I can't comment on the one you mentioned but if it happens to be an exact clone of any of the compatible guns listed here, it will work.

I installed this on my Glock 34 and it just pulls off the slide when I pull it back. seems like the polymer is just flexing under the strain

Definitely have not heard this before. Could be a defective unit. Please reach out to service@recovertactical.com and they will sort you out.

Will this work for a Glock 42 ?

No, but the GCH42 Charging Handle for Glock 42 is.

Greetings. How does this mount to the slide? Set screw?? Thanks.

The upper half and lower half fit over the slide and 2 screws hold it in place.

Will this fit a P80 pf940v2?

Yes, if it has an OEM Glock slide. Otherwise, you will need the OEM P8o charging handle here.

Can you PLEASE sell a parts kit for the charging handles? The UCH17 to be specific. I see you have a parts kit that says it is for the charging handles, but upon opening that item you will see it says the fasteners are m2.5 and the charging handle fasteners are m2 instead. Please advise. You guys are awesome, but I don't wanna pay $30 for a whole new kit when I just need the fasteners/nuts.

Maybe there is some mistake there with the measurements. The hardware is correct for the UCH17.

Pleas make one of these for the Glock 44 in .22LR. THE 20/20 fits the Glock 44 perfectly, but the charging handle does not fit the pistol.

Thank you for your promo reply. I have not, checked other vendors. I wanted to see if your company would modify the design and it would be a great addition to your already impressive line. Now that Glock has fixed the G44 issues it is reliable, and not very companies are making accessories for it as of yet. The G44 fits perfectly and functions great in the 20/20. Without the cocking handle you must use the forward cocking serrations. I also mounted a pistol laser to the lower pic rail and once zeroed it is accurate and makes a great small rimfire package for backpacking and a fun range toy.
