Bud's does not perform and sort of gunsmithing. Your best bet is to take it to a local gunsmith for help.

Good evening to you!! Unfortunately Bud's doesn't perform gunsmith work. Take and contact the manufacturer for warranty work if it was a package deal. You can also go to a local gunsmith or contact the manufacturer of the red dot. Hope this helps. Have a good rest of your day.

Hi Higinio, if you bought it in person, take it back to the store for advice. If you bought it online, take it to a local gun shop for advice.
Good luck, stay safe, & have a great day!

Hi Higinio and welcome. Unfortunately, Buds does not. You would need to contact the manufacturer of the red dot/mount or firearms manufacturer if the red dot/mount was part of the pistol package. Cheers and stay safe!
