I recently purchased a g27 from a guy on glocktalk.  I took it to the range for the first time today and kept having what I thought were jams.  After a closer look, the firing pin was not hitting the primers hard enough.  I then noticed that the slide lock had completely fell out of the gun.  The slide lock spring had actually broke into at least two pieces (I only have one).  There also appears to be a hairline fracture in the frame where the slide lock spring sits.  I have some pictures here for reference.  Is this fracture real?  What steps should I take from here (i.e. call glock or whatever).

TIA

The is from the metal end of the guide rod and in normal in most all subcompact Glocks, nothing to worry about.


This is just a casting mark that does not cover the metal in the receiver and is normal also in most subcompacts depending on what mold was used for the receiver.


I can not see anything in the other photo to be of any concern. Call Glock and they will send you a replacement spring for free. They updated the spring because the guide rod would rub on it during recoil to the point it would break. It does not happen in all the subcompacts.

You should be able to grab the other half of the broken spring with tweezers and remove it. Some times you can turn the receiver upside down and bump it on a flat bench and the spring will just fall out.

From the pic it appears to be just casting marks over the metal in the receiver. The polymer cools faster then the metal so it shows up in some receivers. If you are sure it is cracked call Glock and they will replace it for free.

1. check if your Glock is an early generation Glock for which Glock gives a free "upgrade".

2.  I had the same problem.  Turns out that Glock redesigned those parts.  Imagine.  One day the two parts are there - and the next day they are gone.  Turns out my instructors knew and had replaced those parts in their Glock 23s.

3. I like an excuse to buy spare parts.

Any chance someone knows what years this slide lock upgrade is required for? Or a place to look it up? I tried the glocktalk website and couldn't find any info on the years effected by this.

That is because the internal upgrade that people post about had nothing to do with most problems today. The upgrade that everyone applies to every problem that pops up on the net was internal trigger control parts replacement on 1st and early 2ng gen receivers sold prior to about '92. It has nothing to do with the slide lock spring. Glock redesigned the spring because some would rub on the recoil spring causing spring breakage like yours. Call Glock and they will send you a new replacement.

The new and old style springs.
