| Looking back a few pages in this forum is an interesting post about MIM parts, with a statement that glock now recommends the use of snap caps to prevent breaking the MIM firing pin. So, is everyone installing a new firing pin each time you strip the pistol because of the required dry fire ? Or must we constantly maintain a snap cap in the chamber ? Where does Glock advise the use of snap caps ? |

Last armorer's school I went to, Glock was saying that the dry-fire necessary for field stripping is no problem, but if you do any dry firing other than what's necessary for field stripping, you should use snap caps, because of the MIM firing pin. They explained that "excessive" dry firing (but wouldn't explain what is meant by "excessive") could result in the tip of the firing pin breaking off. The instructor said that, if you dry fire other than what was necessary for field stripping, he recommended snap caps, no exceptions. Take it for what it's worth, but I use snap caps when dry firing my still fairly new G19 that has a MIM firing pin. I've never heard or read of one of the MIM firing pins breaking just from dry firing, but why take chances? Some of the Glock customer reps aren't known for their award winning attitudes (from what I have heard, never gotten one that bad myself) and if you have to call them for a broken firing pin and tell them that you were dry firing it without a snap cap, they're likely to tell you that you voided the warranty.

 Personally I think they want you to use the snap caps because then you got a good double check of clearing the chamber. More to stop AD's than hurt your firing pin.
BTW, always use snap caps on Lugers & Broomhandles. I have broke one of each and those replacements can be hard to find. |

Must be something new. I've been dry firing the sh*t out of all of my Glocks for the last 15+ years and never had it damage a firing pin. I won't use snap caps. You been dry-firing Glocks with MIM firing pins for 15 years?? Verrry Interesting!! Screw a bunch of MIM.  If those morons started saving a few bucks on firing pins at the sacrifice of reliability, they don't deserve the business. I haven't been to an armorers course in about 8 years, but this is the first I've heard that Glock says you can't dry fire. Totally asinine.

| Gotta love terms like "excessive" with no further definition. I have very little tolerance for "grey area" when it comes to tools intended for the most serious of tasks. I frequently strip my weapons, if for no other reason just good old fashioned familiarity training. On top of that I have been in the habit of "dropping the hammer" before putting them away. Guess I need to re-think my habits/procedures. This is exactly the sort of crap I thought I might avoid by going to the Glock system. Silly me. |

Some people dry-fire thousands of times. Prior to the MIM firing pins, there were some reports of breech face failure, which Glock attibuted to that same "excessive dry-firing." I think Glock still repaired the broken Glocks under warranty, but just complained about it.
I don't think Glock means that excessive dry-firing means an occasional dry-fire to disassemble or "put away" a Glock. |

Totally asinine.I agree that I'm not totally happy about all the changes to the wonderful Glock design, but what are you gonna do? They make them the way they make them and nothing you or I do or say will change that. If some aftermarket manufacturer made an exact replica of the old, cast-then-machined firing pins, I'd change out the pin in my G19 and be done with it. I'm not happy about the MIM parts AT ALL, but they do seem to be working, aside from the no dry fire thing. Either you buy a new Glock with MIM or try to stay with older guns without it. But, keep in mind, if you buy any new parts (unless you have a supply of older parts), you'll get MIM and have to deal with it anyway. To me, it's either learn and deal with it or switch guns, but I like my Glocks enough to learn and deal with it. Bub75 |

What is MIM  Metal Injection Molding. A manufacturing process. A cheap one. As for what I'm going to do differently, nothing. I regularly dry fire my Glocks as I have for a LOOONG time to keep my trigger finger and sight alignment in shape. If I have to replace a firing pin down the road, so be it. |
