MEPRO Tru-Dot tritium Night Sights Compatible with Sig p320 sig p226 sig p365 tritium dots Glow on Sight self Illuminated Meprolight Fixed Metal Sights Glow on Sight

Well made, reasonably easy to install and shine better than any other night sight that I have had or seen.

Installed fine on Sig sp2022

As others have commented this sight will absolutely fit the Bersa Series of Thunder "Ultra Compact" or "UC" whether 9mm, 40 or 45. HOWEVER: those are different than the Bersa Series of "Thunder" full size semi-autos. Bersa doesn't make their product line user friendly with the way the names are done. With the UC, like any other quality sight, the installer should expect some mild fitting and filing to ensure a solid connection. With this product I do recommend you spend the extra $20 and have a gunsmith do the sight exchange.That all said, I gave the product 3 stars for two reasons. #1 The color is much more white than the pictured green. #2 The sight is decent in daylight conditions and better than the stock sight. In darkness though (which is why you're considering the purchase, right?) the sight just isn't that bright. I wasn't expecting an empty sky moon but they're not super easy to pick up either. Use whatever brand you can afford but know before buying that the Trijicon and others do have something like a 20% (my estimate) better ability to focus in on.Edit - Follow Up. Well given that the sight wasn't terribly bright to begin with I should have guessed the end result. By April 1st, 2016 the sight has absolutely no light. Not dim or even diminished...it's kaput. I'm going to test the waters with the manufacturer's advertised warranty and see where that gets me. Unfortunately though the extra $20 to have a gunsmith properly install is going to be on me.EDIT: June 6, 2016. After 3 (YES, 3) emails without a single reply I have given up on Meprolight altogether. We all understand (or should) that a bad product example will occasionally hit the shelves. QC can't be everywhere I suppose. That said, the fact that they have a Customer Service email for problems and have not responded to repeated and polite inquiries tells me everything I need to know. Please, do yourself a favor and skip this product and the manufacturer. Combined with some of the reviews shown below it's clear these folks have no ability to respond and fix a product issue.Btw, the customer service email was furnished to me by Amazon so I am confident it's getting through. They either don't understand the problem (being it's a light which has ceased to function inside 6 months... it's doubtful) or they simply don't care. I honestly wish I was dealing with Amazon CS instead of this nonsense.

I have a Bersa Thunder 9 UC Pro. After reading that the sights in this pistol are interchangeable with Sig #8 sights I decided to give these night sights a try.They installed with minimal effort using a cheap sight pusher. To install I did use a metal nail file to file the dovetail on the sights slightly (so that they would push in about 2/5ths of the way in by hand and used the sight pusher to push it in the rest of the way. Both original sights were removed and the new sights installed in about 30min and I'm a novice(first time ever changing sights on in any gun.)Pros: Good looking night sights that works on my Bersa Thunder Pro UC for a great price! The sights have great illumination in the dark. The best part is that the sights (although slightly larger than the original sights on my pistol) didn't cause any fitment issues with my custom kydex holster.Cons:None as of yet.I recommend these sights to both sig and Bersa users.

Put in my p365, works perfectly

You can easily find your pistol in pitch black while camping. they are awesome. bright enough to see them and use them in the dark no problem. one thing I must say is make sure that you check your current heights of your sights and make sure its the right sight for you. it messed up my distance aiming by a bit but easy to compensate for now. will eventually replace front sight with a higher sight to correct the aim. they don't put the sizes on the site at least as far as I can find so make sure you do your homework and ask questions. i think the sizes of these sights that I got were both 8's

I got this night sight set for my dad for Father's Day. He has an UltraCompact Bersa Thunder Pro 9mm. These sights fit perfectly. They are very clear in darkness and are just as good as in the daytime. They are supposed to last 10-12 years. He was very happy with them.

Fantastic, in daylight they appear slightly duller than the original bright white Sig factory sights. Not so much as to make them hard to see in the light, but remove the light like in a dark room, and they glow bright. Not so much to give away your defensive position, but providing a very clear sight picture to the front. I liked them so much, I bought a set for my Smith & Wesson. Somewhat nervous about damaging the slide in the removal of the original sights, I had a gunsmith remove the originals, and install the Meprolights. Did it while I waited ($35). Added bonus, the gunsmith found the original Sig sights in the rear to be 1/16" off center, corrected with the new install. Also he told me that the Meprolight's raised the sight picture ever so slightly which elevated my shot placement about 6" and spot on.
