No, it would require either a picatinny or weaver rail to mount to.
You can use a picatinny riser, but a better option would be to buy the version that comes with the riser already. You can find that option here: https://www.opticsplanet.com/bushnell-ar-optics-1x25mm-trs-25-hirise-3-moa-red-dot-sight.html
Since the centerline height of this optic is 0.47", a 1" riser would be recommended to achieve the closest alignment with an absolute co-witness magnifier. I would recommend the Leapers UTG Super Slim Picatinny Riser Mount, found by using the link below:

The Bushnell TRS-25 Trophy Series Red Dot Sight mounts to picatinny rail. It will not mount to an HK VP9.
No. The Bushnell TRS-25 Trophy Series Red Dot Sight uses a picatinny mount to attach to top picatinny/1913 rails on rifles and PCC's. There are adapter plates and slide milling options for your Glock 44 depending on what sight you choose. I would recommend emailing us at Techsales@opticsplanet.com so we can better assist in finding a red dot sight that will work for your Glock and fits your budget.
Yes. The Bushnell TRS-25 Trophy Series Red Dot Sight can be used for any caliber rifle/pistol as long as it is properly zeroed for each caliber.
The Bushnell TRS-25 Trophy Series Red Dot Sight cannot be mounted to a Glock 19. If you have questions regarding installing an optic to your pistol, email us at Techsales@opticsplanet.com.
You would need to use a picatinny rail base for your rifle if you do not have one already installed. With a picatinny base, this Bushnell TRS-25 Trophy Series Red Dot Sight will fit and function as intended.
Some users experience a slightly stiff illumination adjustment and most of the TRS-25's that I have had experience with have had this be the case.
This would be a great option for a Ruger PC Carbine 9mm.
