Good Evening Everyone,
I have recently noticed that my slide seems to be having some sort of.... for lack of a better term "issue" with the slide and i believe the trigger group. If i pull the slide back and let it slowly ride forward (no ammo involved) it will catch on something and not go all the way forward, it will go all the way forward if i pull back and let go. Also when i squeeze the trigger slowly the slide moves back slightly before it fires. I have never seen any play on the slide during the trigger pull until recently and on my other two pistols, a CZ 75 and a Sig 226 there is non. If anyone has had a similar problem or might know a solution please let me know, or if you might have any diagrams so i can measure to see if there is an spacing issues, or if a role pin might be pushed out slightly.
Thanks
So for anyone that has checked this thread out, I took the slide completely apart, nothing was broken or damaged, also took the lower apart again nothing was bent or showed excess wear. No idea what is going on with my pistol.

you can always send it to SAI for the first class treatment. I just feel like there's something not quite right that probably doesn't require professional attention. if no parts are broken and it worked before but doesn't work now it sounds like something isn't assembled right.
i'd suspect a weak recoil spring except that wouldn't all the sudden create a weird catch point.
as said, if you're stumped, SAI will get it up and running.
What you describe is completely normal. When you creep the slide forward, when the sear starts to precock the striker it will neutralize the recoil spring and stop the slide. The slight rear movement of the slide when pulling the trigger is the striker being fully cocked. Neither affect the operation under normal use.
I agree that nothing is wrong. I have had 6 or 7 Steyrs and every one of them did this, with the exception of my current M357-A1. However, I noticed something different than the previous poster suggests. On every one that I have had, if I pulled the mag out completely the slide would close freely. It will not hang up on anything while traveling forward, so that leads me to believe that it has something to do with the mag itself. It has never effected function, so I never bothered to look into it anymore than that.
I just recently noticed both of these phenomena on my M40 and M357 after a successful range trip -- my first since installing the BT guide rod, spring cups, and new extractor and extractor springs/plungers. I did a search here to see if anyone else had experienced this and I got this thread. I'm not really concerned about the easing the slide forward problem...rather I don't like how sometimes (not always) the slide moves slightly rearward during trigger pull. I noticed that if I tap the pistol downward (pointing downward and then shaking/slapping it or my hand back towards the muzzle of the gun (opposite force direction), it doesn't happen as often. When the slide does not move, the trigger pull feels much nicer and even lighter. I have yet to figure out what is going on, but I am determined to get to the bottom of it when I find the time. Also of note, the striker assembly floats in its tube groove in the slide when the gun is stripped. Possibly, its position may have something to do with whether or not the slide moves during trigger pull. I mainly suspect resistance of the striker assembly has the most to do with it, made worse by something else, such as original position of the striker assembly, which can change shot to shot. I'm not at all sure though.
If the answer has nothing to do with the slide assembly or not entirely to do with it, then I have to take apart the frame and perhaps the trigger assembly to possibly find a solution. I can't get to it for about a week. Perhaps someone else can play detective. Perhaps someone with the means can produce a longer striker rod which fits more perfectly in the channel. In addition to eliminating the floating of the assembly and possibly slide movement during trigger pull, it would reduce or eliminate the snaking of the factory spring and hopefully not affect striker strength much at all. Or an easier solution would be to insert something between the base of the striker assembly and the slide plate (perhaps held in place by an extension which has a hole for the slide pin to go through). Of course, this is if the short length of the striker assembly is a factor.
Okay, I just experimented some more on one of my Steyrs. What I noticed is that if you let the slide slam home, there is a much lower chance of the slide coming back on the following trigger pull. And if it does come back, it is much less. I also noticed that trigger reset is compromised if you don't pull back the slide all the way...perhaps hard. I really have to explore the subframe to try to understand why these things (which thankfully happen during firing) are so necessary.
