So I've mocked up my PSA 1911. I slip on the slide, insert slide stop, etc, rack it, drop the slide anddddd.......it's stuck. By stuck I mean EXTREMELY difficult to pull out of lockup--like bent over, red in the face, cursing difficult. I know you want a tight lock, but MAN, this tight? Barrel link seems to be right, I can slip in the slide lock without a problem. Any suggestions?
I tried the whole candle soot on the barrel lugs trick. It seems as if I'm getting slide/barrel contact on the barrel's forward lug (toward the muzzle) but little if any elsewhere. |

Hood length was 1.312" to first lug groove.
Using nothing but hand power, with bushing installed, I can't get the barrel into lock. Something is binding. There is a clear pivot point without the bushing install somewhere between first and last lug. I've got clear contact on the forward most barrel lug (sharpee is a little worn off) in lockup but I'm not seeing much elsewhere. By hand, I can get the barrel to sit about 0.02" into the slide. Thoughts on where to start filing? |

read this and on 1911 forum there used to be a few stickies about this subject. Read through them and you should be able to discern whats going on. What you're asking us to do is kinda impossible over the internet. You really need to have the part in hand to see whats going on. |

I had to do a bit of fitting and polishing on the lower lugs where the slide stop rests across. When I first put the barrel in it would lock up so tight I needed a rubber mallet to get the slide to move, but after some tweaking of this area it still locks up tight but can be manipulated by hand.

Thoughts on where to start filing? Most likely the barrel hood is too long ( though 1.312" sounds a little short), and keeping the barrel from moving up. Make sure to keep the bushing installed during this test, and the looser bushing fit, the better. You don't want to chase a false positive with a tight bushing at this point. Sharpie the end of the barrel hood, and see if you see light between the breechface and bbl hood when in battery. If not, this is probably where you need to start. I assume the sides of the barrel hood have adequate clearance with regard to the breechface. You need to ensure full and proper lockup in the slide lugs before you even begin to work on the lower lugs. |

Ed Brown semi-dropin match barrel. I'm using the Ed Brown Drop-In kit Brownell's had on sale a few weeks ago. I'll try and post photos tonight showing lockup condition. Thanks to all who have helped thus far. So many different options! On another note, the barrel hood is definitely thin enough that it isn't seeing any interference at the sides of the breech face. How difficult should it be to pull out of lockup? |

How difficult should it be to pull out of lockup? Ideally it should be tight enough that friction will keep it in place. It would pop out of lockup with just a slight press of your thumb. |

WINNER WINNER CHICKEN DINNER.
So, after only looking at the barrel, I decided to look in the slide. There were two clear marks, one on either side, where the barrel sides were hitting the slide's sides. I took just a bit off the sides of the rear lug groove and BOOM. Lockup achieved and I can pull it out as well! On another note, does anyone else's sear/disconnector pin simply fall out without any of the springs in? I don't know if the spring tension would be enough to keep it in or if the pin/pin hole is slightly out of spec. |

No need for press fit or spring tension. |
