Ok, I sent my full 9mm to Burwell to get a trigger job, I get it and the trigger is super smooth.

So I took the handgun to the range and shot 300 rounds, it shot great but after a while I started noticing the trigger was a little gritty.

And after I test fired it with snap caps and the trigger was pretty gritty.

I cleaned the handgun today and the problem got even worst!



Do I need some kind of grease on the trigger parts or something? And does this mean the trigger on my M&P will only be smooth with a very clean handgun?!





Thx!

How long was your gun gone?

What ammo were you shooting? If it were smooth, and then became gritty, my bet would be on the environment. ie. dirt, sand, crud ammo, and the like.



There are other possibilities, like disassembly - assembly errors. If you haven't done that since you rec'd it. this possibility can be forgotten. If you know how to tear it down, do it, clean it, and put it back together - then try the snap-caps. If you do not know, or do not feel secure in a tear-down. It will probably co$t. Try Dan 1st.

He took roughly two weeks to return it to me from the day he received it.



I shot two brands of ammo, "clean" stuff. Some Fiocchi 147g and some S&B 115g (not range safe stuff they are selling now, the old green box).



The handgun was really clean when he returned it because It was clean prior to being sent to him (i know he shoots a few rounds before returning it). But after being shot the gun's trigger was gritty and after being pretty well cleaned it was even worst.



In a piece of paper he sends with the handgun he states "I recommend some kind of "grease" be used on the face of the sear, face of the striker and where the trigger bar contacts the sear. This helps smooth out the trigger pull and prolong the life of the trigger job. I believe lithi grease from steel shield technologies is the best on the market."



But I think its a BIG difference from no grease to a little grease! And if so, the trigger job is almost useless, this could have been solved by adding a little grease myself?

The trigger job is not simply adding grease, lube will nto achieve what a proper trigger job will. Grease does smooth out the trigger job even more, but it should still bea huge improvement over stock even bone dry. A dry dirty gun will be kind of odd feeling, but a lubed dirty gun should still feel like the trigger is a large improvement over stock.



Now assuming you are being reasonable and not blowing stuff out of proportion, have you field stripped the gun and verified that there isn't crud jammed into any of the key areas or that nothing has happened like something chipped or cracked in one of those areas?



-Check the trigger return spring and that it extends and retracts normally. Also check that the cotton damepener is still in it. If it broke, the gun shouldn't function, but all the same, check that there are no bent coils.



-Cheack the sear. make sure there are no chips or cracks. Make sure there is nothing impeding it's movement. It should also return to the full upright position without issue. If it doesn't, there might be an issue with the spring



-Check the trigger bar. Make sure that the doohickey that engages the firing pin block is intact and not cracked or bent. If it has lots of crud on it, give it a cleaning. It should also be lubed in general.



-Check the firing pin block plunger. Make sure it moves up and down as it should and nothing got jammed in it like brass shavings.



-Check the striker. The foot of the striker should have a nice polished face with a clean, square transition to the bottom so that the trigger breaks cleanly. It should not be chipped or cracked. You should also remove the striker and make sure it isn't in the process of cracking from metal fatigue. It will feel strange before letting go entirely. But usually that is in the oduble digits on trigger pulls, so likely not the issue if it didn't creep up as you shot.



I certainly wouldn't call the fiocci I have run into clean shooting. S&B is middle of the road, and the primer laquer tends to get where you don't want it long term.

I dont think asking to properly lube a quality, high end triggerjob with a little grease as part of regular pistol maintenence is asking too much.



If you need to run it dirty, It may not be as slick, but it darn sure will sure work and will be reliable.



I doubt a dirty gun doesnt anything to Dans overtravel and trigger break point; which to me is the most important part of a trigger. I only feel the take up or pretravel, one time; the first shot. This is where you probably feel grit.



I think, on the whole, that most pistol owners under lubricate their guns.



If I had a corvette, Id be making darn sure I kept the oil topped off with the best synthetic oil I could find!

Not taking sides here, just offering my take on this situation:



1. It seems to me that Dan should lube the parts he recommends be lubed as part of his trigger job.



2. I also think that if the recommendation to lube said parts was ignored, you assume the liability for doing so.



3. Just going off the description of the problem, it sounds to me like there's more going on than simply not lubing said parts. I know Mr. Burwell is held in very high esteem and from what i've seen he's very talented at what he does but he is human. It's very possible that something is amiss with this guys gun due to the trigger job so it seems to me that Mr. Burwell should be nothing but willing to inspect his gun and fix whatever is wrong given it's something incurred due to the work he did on it.



I have no reason to believe he wouldn't do exactly that so I'd get in contact with him and see where that conversation takes you.



However, first thing I'd do is get a hold of some high quality lithium grease and after a thorough cleaning, lube up the parts with the lithi grease as he suggested and put some rounds through it to see if that makes a difference. This is, of course, after inspecting the gun as raz-0 posted above.

I will triple check the handgun to see if I can find anything, if i can't i will post pictures. I couldn't find anything wrong with the handgun when I stripped it and cleaned it though, everything looked in place.



Dan contacted me back and said this is not normal obviously and that if I can't fix it to send the handgun back.



Thanks for the help and I'll keep ya posted.

I revised the handgun several times and found out a few things.

The trigger is smooth without the slide on, and could not see any imperfections on the actual handgun.

Once you attach the slide to the handgun, dry firing it with snap caps or just by pulling on the trigger u feel the grittyness. So the problem must be on the slide. Still I could not see any imperfections, nothing out of the normal!

The handgun is properly oiled and clean, just no grease because I don't have any. But the problem apears to be more than just not having grease.



I contacted Dan about it, maybe he knows whats up or I'll just send it back to him for him to fix.



Sucks, but It's not the end of the world! I just don't wanna send it back to him if It's a simple fix.

I notice most of the "grittiness" on the stock gun comes from the interface between the striker safety plunger (under the rear sight) and the trigger arm. This will only happen with slide on. In Dan's trigger paper he recommends changing the profile on this part and polishing. Does it look rough? Another possibility is that something got under it and is causing it to not move smoothly or it wasn't properly lubed and is now dirty.

sucks to be without it, but at least you know it'll be in good hands and the problem will be resolved.
