I am still playing with my gov 380 that has the peened up lugs.
I used some modeling clay and measured up the engagement surfaces and how much of the lugs are bearing.
The front lug has 0.025" engagement. The rear lug has 0.028" engagement. The clay was depressed 0.028" in both of the lugs. The marks on the barrel and the slide match these same depths. The maximum depth of engagement is 0.053" on both the slide and the barrel.
The gun is tight lockup in the linkdown oval so there is not a lot of slop overall. I did notice that the slide lugs while rounded are not peened up. The firing pin mark is centered in the ammo, and the gun hits close to point of aim. Thus the barrel is centered in the slide or at least where it is supposed to be.
The gun does operate (with the spring out) with no hitches upside down or right side up. There is no binding due to the peened metal yet.
My interpretation of the situation is I need a new barrel with more lug engagement. This I could then fit into the slide correctly.
I am just worrying about nothing? Is 0.028" enough engagement for a 380?
Any thoughts or comments?
Thanks
