Since I mounted the Delta Point the 34 has become ammunition sensitive. Specifically, it will not function reliably with lightly loaded 115 grain ammo like Federal or Blazer Brass. On average once per full magazine, a round will fail to extract or will short cycle and not pickup the next round in the magazine. It runs 100% with hotter Speer Lawman and with Blazer Brass 147 grain. Has anyone else experienced this and can recommend a fix?
