Carlos:
Just for fun (?
), pop the RAM out of the gun and see if that changes anything.
The RAM shouldn't affect anything unless there are other serious problems in the gun.
However, if it's not properly installed, the gun's not going to behave all that well.... The RAM is supposed to grab the rear end of the trigger bar and pull it towards the centerline when it's not being moved by way of the cam surface on the underside of the slide. If you install the trigger bar improperly, the gun shouldn't fire.
All the RAM actually does is help the trigger bar get back into place for the next shot, whether or not the trigger spring is present, but you could assemble it incorrectly. The tip of the trigger bar should ride inside the notch on the end of the RAM. That it makes a bit of noise (in some cases) to announce a reset, is really almost a coincidence, but don't tell Apex I said that
....
Another issue - did you install the new Drop Safety (can't remember what Apex calls it)? If that's not done properly, the drop safety plunger may be holding the striker back a bit, causing light strikes, or no strike at all.
Maybe one of those?
I had a buddy with a Llama Firestar (.40S&W) that would only fire some handloads that a club member was making. "Factory" loads, including my "you bought WHAT?!" reloads, wouldn't fire.
Turned out that the drop safety system in that gun was out of time, and the firing pin was hitting the bar while trying to fire. This raised a divot on the bottom of the bar that held back the firing pin - not completely, but enough to cause issues with hard primers.
Anyway, Carlos, have a look at the location of the trigger bar inside the notch in the RAM, and see if you can figure out whether the drop safety is installed properly. It should move easily.
Scott or Randy probably can toss some more suggestions out. I think Scott hangs around here.
