PSA: 2019 Glock MOS Pistols-Clean Em Prior To Carrying.

[Magsz]

Heya guys,

I just picked up a new MOS G17.5 pistol starting with serial #BKF (https://pistol-forum.com/usertag.php?do=list&action=hash&hash=BKF) . All of the pistols in the case had plastic shavings in the striker channel from either the spring cups or the striker channel liner being inserted into the slide. Anything in the striker channel can and will eventually cause issues and pieces of plastic is a surefire way to end up with a light strike.

Ive never been one to clean a pistol out of the box. I've always taken them to the range, checked for a bore obstruction and started shooting them. If a pistol failed, I would diagnose the why after the fact in the safety of the range or my own home. Given the sheer amount of plastic present in the striker channels, a few seconds cleaning that crud out will probably go a long way to prevent possible heartaches.

Anyone else seen this on new production Glocks? Im not bashing the company or their QC at all as I hardly care as I think the gen 5 is their finest creation to date, I just might change my usual plan of attack and clean out striker channels on new guns from here on out.

Just a little PSA/observation on my part.

I always detail strip, clean and lubricate my pistols before firing them.

Sorry, but... Duh?

Its a good practice to clean and inspect EVERY new gun you get

Why? Short of a bore obstruction, who cares? Ive never cleaned and inspected any firearm i've ever gotten out of the box, ever. I've never had any issues. Short of a function test, what the hell are you looking for? I don't white glove my gear and I don't give a damn if the barrel isn't perfectly centered in the slide so long as the gun can be zeroed.

Over the last ten years I've purchased 30+ Glocks and never had a single one with any kind of debris in the striker channel from the factory. Ive handled and worked on probably five times that amount. Given my recent observation, I figured I would post about this as a heads up to everyone.

It's just an observation, on a forum, where we share observations. It's also a forum so I cant detect true tone but your "e tone" seems disrespectful.

I lube new guns and shoot.. I would of never thought to check that. I have had issues from basically every major manufacturer now. Colt, bcm, daniel defense, and others... Trust but verify seems to be the new way forward.

Well... I don't clean before shooting a new gun but I do inspect. Many many moons ago, my department carried 3rd gen S&W 45 ACP pistols. After being inservice for about 3 years a good number of them went tits up during quals. All were having light strikes and did not ignite the rounds. It was revealed that our entire batch of that model had an excessive amount of Li grease in the firing pin channel. Over time it gummed up and caused a failure to fire. Fortunately the problem surfaced during quals and not in a gun fight. Inspection at the time of acquisition would have revealed the presence of the grease and allowed it to be removed before placing the pistols in service. Since then, I routinely check the guts of new pistols. Maybe that's excessive but it is only a little effort for a potentially huge return.

When companies assemble their guns often they use a preservative oil and not a lubricating oil. Cleaning the gun before hands lets you remove that preservative and replace it with lubrication. It's not about white gloving it.

Same here, same fine results, almost as many Glocks. Thanks for the heads up!

I didn't mean any disrespect, but its a well known and common practice to strip, clean, and inspect a new firearm

You are placing LOTS of trust in a companies QC department, and from your OP, you got the exact reason why many people don't just load up their guns straight out of the box

[theJanitor]

I've never stripped a gun before shooting. I perform an applicable function test, lube, and go for it. On a new brand/type of gun, I won't consider myself an expert on the system either. There's no saying I'll put it back together better than the factory assembled it, so I leave it alone.

Do you guys strip down your new AR before shooting it? Like, take apart the FCG, or the BCG? I sure don't and I don't know many people that do. Rifles get a pass and pistols, don't?

[rathos]

I used to do this with all pistols and rifles. Break it down as far as possible for me and clean EVERYTHING. I stopped doing it with glock pistols as I was told the copper stuff is supposed to be there for "breaking" in the gun. At most I take it apart and lube it and clean the barrel then shoot it. For rifles I still break it down in a detail strip and clean and lube it all. I generally have at least a week or two after buying a gun (open range days are usually only every other week) so why not take the time and make sure you gun will function?

however, I wouldn't give any one shit if they just took their gun out and shot it without doing that.

[theJanitor]

My AR's lowers are factory Colt. I leave the trigger and keep the four position RE, as the whole point (for me) is to have a factory assembled lower. I trust those more than ones I assemble. And the BCG? I just make sure there's friction when i move the bolt back and forth.

I know that this discussion is in the Semi-Auto forum, but I really don't think people apply the same rules to rifles and pistols, and that makes less sense to me. I mean, who details strips a bolt gun or a shotgun before taking it to the range for a zero? Not many, I recon

[RevolverRob]

A connudrum I’ve thought about. If I take a new gun to the range, shoot it, then take it home and detail strip and clean it, how am I positive it works without shooting it again?

Sure I can use a snap cap and confirm the firing pin drops, but I can’t check all functions.

Where as, if I detail strip the gun first, check everything, and then take it to the range, I’ll know if I messed something up during dis/re-assembly. I then just wipe the gun off, since I cleaned it and applied proper lube prior, nothing should get gummy.

I’m also only inclined to detail strip a gun when replacing parts or cleaning the initial shipping gunk off of it. Otherwise, I like to not fuck with it too much. Over the years I’ve gone from an obsessive gun cleaner, to someone that wipe the dirt off their gun with a mostly clean rag.

The Copper Anti Seize has never made my gun explode or impeded its function. The days of MOST guns being shipped in Cosmoline are over. Add lube and go. You don't need to remove any "preservatives" as they have zero effect on function. I've prove this to myself with numerous firearms and numerous 2000 round tests.

Its up to you to determine what your practice is. If you want to detail strip the gun, rock on, have at it but to say that its a "requirement" or imply that I'm stupid, uneducated or a "noob" or whatever someone might want to say is ridiculous. The implication that this is "basic" knowledge is false.

The gun either functions or it doesn't. You test function in a safe environment and address issues systematically as they pop up. If they pop up.

Trigger is really hard to mess up honestly.. you have to learn to field strip it to keep it clean honestly, we quite a few m4 triggers fail to reset because guys were not cleaning out their lowers.

[Joe in PNG]

I clean more than most here not because of any fastidiousness, but because I honestly like taking guns apart.
Cleaning is pretty much just the excuse.
Now, I usually do a quick fieldstrip and clean of my new guns, but seldom get into detail stripping.

Just that reason that a special operations friend of mine used to insist on cleaning at the range, and running a mag through the gun after it was cleaned. When he left the range he wanted to know that the gun worked. I have seen experienced, switched on guys have a brain fart during reassembly and not do things right.

Pencil check also helps.

True, but I had a Gen 3 19 that passed the pencil test and I still got light strikes. Plan A was to swap out strikers on the spot, and when I looked down the channel there was a plastic shaving bouncing around in there.

Admittedly that's pretty rare and I wouldn't say you should always check for it, but it's not impossible either.

Beretta has gone on record as saying that they ship their guns with a preservative oil (not cosmoline) and recommend cleaning and lubrication before firing to remove that oil. While usually there isn't a problem, I've read the accounts of more than a few folks who had trouble with their NIB Beretta that suddenly went away at the next range trip after cleaning and lubing the gun. I don't know of the other manufacturers, and Glocks seem to have a reputation for not requiring this, but it's probably something to either know ahead of time in relation to the vendor and manufacturer, or, if it were me, to err on the side of caution.
