The advice about the frame cracks, use only standard velocity ammo, and change the driving (recoil) spring are all very good advice. You do need to keep it in perspective, that advice is given because the High Standards will last generations. If a person is looking for a 10-15 year pistol, one could do anything they wanted to a good High Standard and it would likely hold up that long (or longer). I compete but not as much as I used to and testing has shown the High Standards, particularly the new Houston Texas models, to be very accurate. I put them against some good .22s. There are 3 High Standards on the bench in this photo. In my range rack i have a Hammerli 208, a Benelli 90 World Cup, a Pardini SP, a FAS 602, a Browning Medalist, and a Russian IZH-35M. None of those guns group better than the High Standard. Hope this helps.
