This weighs 5½ Ounces.

Michael, this is off the table at a Weight of 5.3 Ounces and Length of 3.27". The Bushnell Advance Micro Reflex Sight 1x5 MOA Dot meets Kel-tec's requirement :budsgunshop.com/product_info.php/products_id/712014650/bus+micro+reflex+sight+blk+red+dot ---- Cheers and stay safe!

Michael, the weight on this is 5.5 oz.

For under 2oz you probably want took at pistol RDS, there are plenty that are built tough enough to handle Keltech recoil
My favorite is the Holosun 507C. Weighs 1½ ounces it cost a little more then the truglo but you get way more.
Multi reticle (32moa cqb ring, 2 moa dot, or a combo of the 2) it is selectable so you don't have to buy just one reticle you can cycle through them. Also 50 000 hour battery, solar back up, side load battery tray and shake awake.
Buy once cry once

A little less expensive would be the Vortex venom or viper, but the 507C is an excellent choice
