I am not sure. I think the "spongy" trigger is part of it. I have not had a failure with it. I might have 150 rounds through it.
I go out to the safe to pick out what I am going to take to the range.
I pick that gun up. . .and put it back. I have never used the holster or the mag carriers and bought two more mags when I got the gun.
I really should sell it. I just know I will kick myself in the rear if I do.
I have a 4506 and a 5906 that I treat the same way. I just do not shoot them.
