    Are all Generation 4 Glocks having problems with mounted rail lights and FTF's?
    Or is it specific models and light combinations?
    I've seen videos of G19's displaying this problem but wasn't sure if other models were suffering from this as well
    thanks

    Wow... this is news to me. I know Gen 3 G23's were known for this issue, but that was the only model in Gen 3. Now you're saying the G19 and others in the Gen 4 may have this issue?? I find it hard to believe Glock would produce another gun with this issue after the G23 of Gen 3 created so much discussion and concern.

    My apologies, it's not FTF's that is the problem, it's the slide dislodging from the bottom frame

    the first comment response says the problem was the slide stop spring.

    it also looks like the gun is working properly now according to other comments.

    I just got back from the range this AM with my gen 4 g19 and its TLR-2. No issues in 100 rounds.

    This was brought up a while back when this video first posted.
    Eventually it was proven that this weapon's slide lock was installed backwards.

    Not necessarily factory error.

    Exactly, probably not factory error. Those slide locks are easy to put in backwards if you don't pay attention or don't know how to put them back in the right way. Make sure that notch is up and back.Otherwise, the barrel can't lock into it properly.

    Hey guys. That's actually my video. Yes Glock fixed it and did say that some Glock 19s left the factory with the wrong spring. The serial numbers to look out for start with PPZ and were test fired late June 2010. HTH.

    Thanks. My buddy Joe was filming me and did a great job on focusing on what needed to be done.

    1675 rounds downrange so far 300 of them with the light mounted. Not a single malfunction of any type whatsoever. Most of the rounds are Wally-World Federal champ. 180gr fmj,with a couple of boxes of WWB 165 gr fmj and 50 rounds of Gold Dot 180 gr jhp. Not a single hiccup! I suppose if you used a coin or screwdriver to REALLY tighten down the light it might flex the rail enough to interfere with operation,but then I suppose if you plugged the barrel with a potato that might cause a glitch too! :supergrin:

    Nope no problems with the slide stop and the TLR-1 installed. FTE is a new story lol. Yes luckily there were no injuries with that malfunction.
