EXCELLENT!!!! As the Terminator says; I'll be back!

I ordered adjustable sights for my CZ 75 Shadow, but accidentally ordered the wrong one (without the white dots). I sent a mail on a Sunday, and that was answered the same day, and the order was changed instantly. The right set arrived from the Czech Republic to The Netherlands on Tuesday morning.

Thanks for the Excellent service Paul.

Beretta 92x Optic Plate Type B - AWESOME

Don't buy this from any other site...Optic Spot INCLUDES the pin set that you'll need to mount your optic, even the Beretta site does not include this. Was a PERFECT FIT and high quality!

Sig Sauer P220, 225, 226, 227, 229, 320 red dot mount universal | type B
PERFECT FIT - EASY TO INSTALL - SUPERIOR PRODUCT -Thrilled with purchase

I bought another mount (from a vendor in Quakertown, PA, USA) which was horrible, badly machined, so badly machined I had to use a file for hours to make it fit on a HK VP9. Then, I went to Optics-Spot, for my P226 Legion needs.

John, the customer rep., was on the phone with me for fifteen minutes at 2:00 AM (Eastern U.S. Time). He found this perfect mount for my Sig Sauer P226 LEGION (in .40S&W caliber). This gun is very rare and highly-collectable, so it was essential the mount fit perfectly without marring the pistol.

It fits PERFECTLY. Instead of hours of filing, just drove it into the dovetail with a hard plastic-faced hammer and it snugged-up PERFECTLY. Set screws for the dovetail fit and tightened perfectly, also.

This "Universal Mount" comes with "drop-in" lugs (keep the reflex sight from moving horizontally) which appear to be machined to 0.0001 inches, or better, so tight that there's no measurable movement but they dropped-into the recesses amazingly well.

This is a VERY, VERY IMPRESSIVE, QUALITY PRODUCT, sold by a superb company, "Optics-Spot," with extraordinary customer service.

Cudos go out to John, and Optics-Spot!
