Hey Bob I would like to add
I own a lot of Rugers although no Semi Auto Pistols
I do own revolvers and I have had a bad one or two, but Ruger stands behind their products and I have had a GP 100 replaced and a Super Redhawk 44 mag. The first thing before shooting I take all my firearms apart and in some cases to the point I have to call the manufacture because I tore them down past the point of no return.
When shooting any caliber firearm remember You Are The One holding that firearm. I shoot a lot of .357, 41 and 44 Magnums using factory loads. I have seen the results of these firearms blowing up in one's hand and it is not pretty. Some of problems the shooter was responsible for shooting reloads by over loading powder requirements and yet Ruger still replaced the firearm. Others have been a manufacture problem, mostly timing on the revolvers and Ruger has replaced/repaired but it is up to the individual for checking the firearm out prior to shooting.
I learned from some of the best Bullberry Barrels, TC, Sierra Bulletsmiths and World Class Shooters when I did compete with a Remington Model 700 ADL .308 Winchester with a Sierra 155 gr HPBT PALMA Matchking at 1000 yard targets. I still shoot rifles just don't compete like I use to, however, when you shoot 300 Win Mags, 338 LaPua Mags and 7mm mags you best better tear those rifles down for the first time even if custom made. My favorite rifle I love shooting in a Browning BAR that I have in 270 Winchester this is one bad bear that I have compensated as the rounds fly out of that rifle.
Remember people make mistakes
