    Ok got a nice new little 9mm hole in the man cave wood floor. Earlier tonight was loading my Rock Island 9mm. Slide was locked back, inserted mag, made sure trigger finger was not on trigger or inside trigger guard, pointed gun at floor away from body, dropped slide with slide release. BOOM.

    Scared the crap out of me, wife, daughters and dog, it didn't seem to bother the cat he came running in and started sniffing and licking new hole in floor. :p

    Slide didn't not even cycle after firing, I hand ejected spent casing.

    Ok what do I need to be checking?

    Sounds like hammer follow. Could be a problem with the sear spring, sear or hammer. Do RIAs have a firing pin block?

    No firing pin block or safety, they are like a Series 70 Colt.

    bubba that's over my pay grade but I hope you figure it out. Everybody I know with a Rock Island is happy. Good luck and be careful.

    Basically, had it a while, but haven't shot it much, probably less than 100 rds.

    That's what puzzles me. Hope you find out what's wrong, so you will have faith in your gun.

    Well that makes me wonder myself now. Having A RIA 1911-45 and a Citadel 1911-9 if the possibility is there to happen on either of them?

    Glad it was just the floor with a hole.

    I would contact the company and ask them. They may let you send it to them to be checked out or take it to a smith of their choosing. Either way I would let someone look at it soon. Glad you have the training to keep the muzzle pointed in a safe direction so no one got hurt. I bet your ears are still ringing!

    Two possibilities here that I can think of off the top of my head.
    1) Hammer follow (as has already been mentioned).
    2) weak firing pin spring
    Actually there's a third possibility
    3) protruding primmer
    I would first take a good look at the primmer on the expended case. I'd look for things like rub marks; a weak or shallow strike versus a good solid indentation from the firing pin. You say the gun didn't cycle or eject the case? Was the hammer fully cocked AFTER the gun went off? Look at the case; does it appear the gun was fully in battery when it went off? Any bulging of the case? Has the gun had any work done to it; such as trigger work / replacement parts?

    You can also put a couple of snap caps in the magazine and release the slide on them to see if you can get the hammer to follow.

    It really shouldn't be hard to diagnose.

    The disconnector safety should have prevented any out of battery discharge. I'm guessing sear-disconnect-grip safety, trigger
    3 pronged spring unserviceable or short or rounded disconnector. Since hammer didn't cock, most likely that spring broke, at least two prongs anyway.

    I think Rogue is on the right trail. Maybe a high primer caused it to fire out of battery. That would explain why the spent case was still in the chamber. Gasses would have escaped before locking into battery and not ejected the spent casing.

    Like others have said, just glad it was the floor and not a body part. Hope you get it figured out.

    Case look normal, no bugles, primer not protruding, looks like a solid strike to me. Hammer was down after gun fired. No work done to gun.

    Gonna take it Bill's in Shelby let him check out.

    Yeah if the hammer was down then you had hammer follow. Should never happen with a factory gun; not even on an empty chamber.
