I have carried SA 1911's for years and have never had a problem.
The TRP Operator's are semi custom and although they use factory parts those parts are hand fitted to the gun. They literally start off as a box of parts at one end and are hand fitted all along the line. The TRP Operator's are only made twice a year one run in spring and one in fall with 100 of each model built. Each part is numbered to the gun.
