The truth is, those that are hell bent on believing that dry firing isn't good for the gun, will absolutely never change their mind. Even if their owner's manual said that it was OK, or even said you HAVE to. Even if the company emailed them and said it was ok. They will maintain the attitude that it's "Better safe than sorry". And there will be those that change their car's oil every 3,000 miles because Jiffy Lube put a sticker in their window. Even though the owner's manual clearly states every 5,000 miles. Again, to them, it's better to be safe than sorry. And they won't debate it with you. They will say: Do whatever you want with your gun, and I'll do what I want with mine. That is definitely an option, and totally acceptable. But it also means that some people don't care about the truth. They only care what they think. Right, Wrong, or indifferent.
The best suggestion is to:
1. See what the owner's manual says. If it says yes, then the answer is yes. If it says no, then the answer is no. If it doesn't say either, then see #2.
2. Email the manufacturer and ask them about that specific firearm. Now I recommend you to be specific in your question. Because of liability, many people, even at the company, might tell you to not do it. Also, manufacturers usually make numerous models. It's quite possible that some can dry fire and some shouldn't. Be specific on asking about your gun.
That is how you can determine what the right answer is. Now, there will be some that email the manufacturer with the HOPES that they'll say no, don't do it. Then they can come to a forum like this and say: "I told you so". However, if the manufacturer says yes, it's perfectly fine; they'll claim the person at the factory doesn't know what they're talking about, and they will still believe and say that dry firing is wrong. So it's a no win situation.
