Just got me a new Shield 45. I'm cleaning the packing oil off amd when taking the barrel out of the slide the chamber area is very tight against the slide. I can remove the barrel from the slide but Ive never had a pistol barrel this tight to remove. I'll post some pictures below . The squared portion of the barrel against the slides rails is very tight. Do any of you 45 owners have this same thing ?

I don't have a Shield 45. Chiming in to see what others may have to say. Does it talk about this in the manual?

Nothing about the tightness is mentioned in the manual. I've field stripped it , cleaned it and put it back together but it's really tight in the barrel chamber to slide rail area .

It kinda seems like SW used the 9mm and 40 slide and just made the hole for the muzzle bigger to accept the 45 barrel . I'm sure this isn't the case but it's the best way to describe the situation. I went in my backyard and test fired it. It ran great .

I have had M&P 9 2.0 for a couple yrs now and also noticed that when it was brand new that turning the barrel in the slide it would lock in also. I don't notice that happening much any more after over a thousand rounds thru it.

No its not the barrel portion , it's the chamber , breech or "squared portion " of the barrel that is tight against the slide's rails when taking it out and in. There's almost no room for error it's so tight.

I like to put a thin coating of oil around the barrel, chamber sides, lug, hood, and on the insides of my .40 Shield slide with a Q-TIP after each cleaning.

I would agree with Rick M on post #7, just lube it lightly and it should work itself in nicely.

Is it functioning correctly?

Don't fix it!

I have two M&P9 2.0s and the barrel hoods have to be carefully aligned when reinstalling the barrels into the slides. Otherwise they stick and have to be jarred loose. It seems to be typical.

No offense but I dont think you guys know what I am talking about. It has nothing to do with the long part of the barrel. Only the squared chamber area. When the slide is off and laying upside down , when I lay the squared off portion of the barrel (the chamber area) into the slide , this squared portion wil barley fit into the slide. It rubs very tightly against both sides of the slide.

Post 11 is saying the same thing you are.
I believe his description is using the proper words "barrel hood", but you are both talking about the same thing.

Ok I went back and read it again. I think we now are on the right track LOL . Seriously though , I have never had a gun with this kind if tightness. My other M&P's are normal and have plenty of wiggle room.
