All Bar-Sto Pistol barrels are machined from solid stainless steel bar stock which has been heat treated 39 to 43 RC this gives 180,000 PSI tensile strength. Barrels are machined,and rifled completely in our own shop. Accuracy out of our barrels properly fitted can be 1" or better at 25yrds. All barrels have a rate of twist of 1 turn in 16". We have been doing the same thing for over 35 Years.
We have been involved in many special projects and custom jobs and have seen and done just about everything at least once. We are still the standard by which all others are measured. We strive to provide the VERY best and most consistant product on the market. We are a family run and owned business.
