G30 Slide Lock Spring Booboo!

Was shooting at the local indoor range this weekend and had a real peculiar thing happen; pulled the trigger and there was just a "click" and the slide moved forward a little bit! Nothing else! The slide actually moved forward about 3/8".

I racked the slide, unloaded, removed mag, check the chamber and left the firing line. We checked out the gun at the desk and the slide lock fell out on the desk! Tried to remove the slide and could not until we viewed a broken slide lock spring hanging in the gun. We finally got the broken spring out of the G30 and then removed the slide. One of the owners of the range is also a Glock Armorer; pulled his manual and checked out the broken spring. The spring just snapped at the formed bend where the spring is inserted into the polymer frame. Anyway I have a slide lock spring and a spare being sent to me in the mail.

A little note here and some of you may already be aware: the part number given in the manual for the slide lock spring should be verified. The correct slide lock spring for the G30 is the shortest one you can obtain; it is roughly .580/.625 long and generally has a side view that looks much like this ~

Anyone out there have this happen before and if you did is there anything else that you've learned should be replaced in addition to the slide lock spring? Yep, I did order another slide lock too although it looks fine.

1st time I ever shot a Glock a 30 I rented at the range. Same thing happened. I nearly lost my desire for a Glock at that point but the owner told me the gun probably had 100K rounds thru it and got cleaned 2-3 times a year. It's not a common problem but like anything else, parts break and wear out.

Mine broke when my bro was putting it back together. After that i bought a couple spares incase that happens again. according to glockmeister that part is sold quite often..

Yeah, that thing does break but I guess it's just the "Glock aura" that surrounds this gun and you think "...nah, can't be broken"!
I still wouldn't trade it off. We just went through a 2 day training session on Advanced Handgun Techniques (John Farnam)and we put a minimum of 600 rounds down range. I did not see one Glock go down but I did see a 1911 go down and a Kahr. I'm not saying this are bad guns...I'm just making an observation known. Majority of the guns were Glocks.
Granted, this was self-defense / combat type of shooting and not slow fire target so you're looking at a different animal altogether.
Hate to say this ladies and gents but I have a Springfield XD 9MM on the way in June. I've been impressed by the little bit I've seen; also shot my brother's XD. I'm hoping it has the best of both worlds in that gun. It's Glock-like enough to draw my attention, the price is right, and I do like that grip safety. Oh yeah, I know, the safety is the one between your ears.

Mine broke at around 6,000 rounds.
