XD-40 Subcompact: First gun owned, have questions regarding discharge noise, grain
For my birthday today, I received an XD40 Subcompact from a good friend of mine. It came with a standard-capacity 9 round mag, and 2 12 round high-capacity mags. Seems like a quality piece so far.
Anyways, I have some general firearms-related questions, along with a couple XD-40 specific ones. I'd appreciate any help you guys can give!
- What does 'grain' mean? In the XD40 manual, it says I should use 140 - 180 grain ammunition. The ammunition I purchased today was Federal .40 SW 180 grain FMJ. So what exactly does the 'grain' mean?
- How loud should a .40 caliber handgun be? When I fired mine at the range today, using the above ammo, it sounded like a mini-cannon. Having never owned a handgun before, I'm unsure how loud 'normal' is, but this seemed really loud! Is something wrong with my gun? Also, I hope I don' t have to use this in my home, because I'd go stone deaf after a couple shots!
- What's the effective range for an XD-40 subcompact? I was thinking maybe about 25-30 yards with the 3" barrel?
Great, that's it. Thanks in advance for any replies, really hoping to get some info!
