.Hello all I have told you about a gunsmithing company in WV called Lightning strike technology they were going to build me a 10mm on a colt officers frame well the screwed me over and ruined my gun they were to fit another slide to my frame well here's what the new gunsmith said and what damage they did. Here's his email. Chuck I will give you a call Friday. I have inspected your gun and it i...s not good. We can discuss in detail. The short list is: Barrel and bushing not set up right. Each time the slide goes back, the bushing runs into the barrel and is being pushed out the front of the slide. Bushing is damaged and so is slide. Barrel feet are not cut correctly for short slide guns. Talk to you Friday. Alan So please pass this along to anyone considering using LST DON'T USE THEM THEY ARE NOT RELIABLE NOR IS THEIR WORK I KNOW FIRST HAND
