Welcome to the forum DG. Sounds like another good experience with the SOLO. I have been able to shoot 115gr JHP through mine, but have had issues with cheap, target 115gr ammo (Winchester white box, Georgia Arms reloads, etc..). I’m certain that it’s not a matter of how I grip the gun. In fact, I purposely limp wristed it with some premium ammo and had no issues. Did same with my R9 when I first got it and couldn’t get the thing to malfunction no matter how hard I tried. I agree that the mag release does take some effort to operate, but I did have one come loose in a IWB holster. I blame that on the holster though. Is it possible you didn’t have the magazine seated all the way? On a full mag, it takes some effort to seat. I’ve shot about 25% of my rounds to date one handed and the gun worked great. I’ve got 350+ rounds through mine and plan to take it out this weekend too. So far, I am pleased with it. It is accurate, dependable (with recommended ammo), and not a bad looking piece. Please keep us posted on your experience with yours.
