I do NOT want to get into a "religious battle" here, but I was asked to pass this info along by a senior technician at Glock-USA's customer service department, so here goes! [If you doubt it, please contact Glock and ask them yourself, don't blame me . . . I'm just the messenger. ]
- Glock-USA told me that we SHOULD use snap-caps for extensive dry fire sessions.
- That the pictures of "punched out" slides I've seen and the damaged product that Glock has replaced are due to repeated dry-fire sessions without anything to support the area that a case would normally occupy in the chamber.
- Glock has NO caution in the manual (the technician told me that this was an oversight/mistake on their part), therefore if you don't do this and punch out a slide, they WILL replace it under warranty. But this is a risk that you run in not using snap-caps.
End of Glock customer service message.
-----------------
Personal opinion follows:
- I've seen the pictures on GlockTalk of punched out slides. The damaged area is approximately the same size as a cartridge rim.
- I have a degree in EE, but we had enough Mechanical Engineering courses to understand something about materials.
- My engineering background tells me that the damage that I've seen pictures of and the admonition by Glock's technician correlate as most probable "cause and effect".
- In summation, I think that Glock is correct in asking us to use snap-caps.
Again, if you doubt what I stated above, please call Glock and ask them instead of arguing about it here.
Thank you.
