I had purchased a hand gun from other dealer a few years back and did not like the sights. Had to hold 8 inches high and to the right to come close to the bull’s eye. I talked to Keven about changing to a setup more fitting to my needs. Keven quoted me a price to change out the sights over the phone after I explained being color blind. Keven recommended what he thought would be best and changed the sights. Keven broke the tooling used to change the sights and still stood by his word of the cost. when I fired the weapon, it was spot on first shot without having to make any adjustments. only shot three rounds and was more than pleased. I will be continuing my business with Kilo Charlie GIANT THANKS.
