Hi, All: I went to the range yesterday to test gun returned from factory. They replaced slide, and "tweaked" the springs. I ran 3 mags with 6 rnds. and had FTF on same rnd. each time, but gun was right on target. I was able to pull slide back slightly and then it would feed stuck round. I may have limp-wristed in my effort to rapid fire. However, one mag was shot one-handed with same result. I finally ran one mag of Win Silvertips which I have had for years. They ran flawlessly! I believe Maria told me that Eric Rohrbaugh uses Silvertips in his gun. However, she said: "But Not the 'white box'. Does anyone know which box she would be referring to here, and if it is currently made in standard pressure. BTW, the report and recoil on the ST's and GD's very similar. My first concern with defensive carry is that it go Bang! Even if round is older tech. I cleaned and lubed again. No trouble with dis-assemb.or re-assmb. Thanks to you folks on the Forum. Larry
