This is a very nice enclosed red dot sight. It installs easily, it works very, very well and it sits rock solid on a Sig Sauer GT4 pistol. Couldn't ask for anything more.

I wholeheartedly recommend this sight, particularly for the application mentioned above.

This plate lacks the anchoring posts for the Holosun K footprint, which is why I ordered it and what this review is exclusively focused on. Their customer service department stated that the two screws that attach the sight would be enough if they are installed following a procedure that dictates that each screw is tightened a little bit at a time and loctite is used. While this is good advice when tightening any red dot sight or scope (to insure even tightness), this by itself will not insure return to zero if the sight ever needs to be removed for any reason. Without the two anchor points, this plate should not be fully trusted with the HS 507K or any other red dot with a similar footprint. It is being returned and replaced.
Also, when something claims to be good at everything, it is generally mediocre - at best - for everything. I should have known better...

The Saffiri products are terrific! This slide is made by them and lives up to its expectations. It is a very nice looking slide but,, ore important than that is is lighter because of the cuts as well as quicker to cool down. I recommend this product 100%.

This is a Zaffiri product, what else is there to say... The barrel performs as well as expected of a high end aftermarket upgrade. It looks particularly good in a Zaffiri slide, but it looks very good in an OEM Glock slide as well. This is so because of the heavy crown and the flush fitting of this barrel. But, as we all know, how well something looks in a pistol isn't everything. Every element should also work seamlessly and this particular barrel shoots quite well. It is also a drop-in that requires no fitting at all but locks in as tightly as any other barrel does, and, perhaps, better than most. I recommend it with 100% certainty.

Leupold's DeltaPoint Pro is a great improvement over the original DeltaPoint. It has taken out all the initial weaknesses from the original and Leupold has now produced an impressive, dependable, easy to install and use reflex sight that, in my opinion, is second to none and less expensive than most of the class "A" red dots. Leupold has again lived up to its impeccable reputation.
