Hi all,

After taking a class at the Firearms Academy of Seattle a couple of weeks ago, I began to notice small problem in my P99's trigger.  In the long SA mode, I now feel a "catch" about halfway between the fully forward location and the SA set point.  I can't feel it in DA, but that might simply be because the pull is so much heavier.

The pistol has 600 rounds of mostly Winchester White Box through it, and is regularly cleaned (field stripped, Hoppe's for the barrel/slide then oil). Perhaps I have some crud on a trigger mecahnism surface.  How would I clean that?  Any ideas would be much appreciated.

Additionally, I wanted to relate some problems I had during the class.  I'm a complete novice - those 600 rounds through the P99 are the only pistol rounds I've every fired.  At the class (FAS-1, which was not only instructive, but also great fun) we did a series of reload drills.  What bothered me was the long SA pull after reloading from slide lock.  I'm more or less used to the DA/SA transition, but had never really thought much about the long SA mode.  Well, every time we did that, I pressed way too hard, expecting DA since the trigger was forward.  Needless to say, I threw every shot.  I suppose that more practice will solve that, but wondered if anyone else was distracted by that mode.

To be honest, I'm now a bit confused about why the long SA even exists.  If you carry with a round in the chamber and decocked (as I assume most do) then then only time you'd see that mode would be during a reload.  Help me understand what that buys you.

Thanks in advance for the help.

Ni3Frontier,

There is basically is very short duration increase in the pressure required to move the trigger.  It literally feels like there is small bump - I can also feel it if I let the trigger back out.

I've been looking back through some old posts and wonder if it might be time to do the Simple Green dunk.  Maybe it's just really dirty.

Thanks for your reply.

P88,

Thanks for your reply.  I've probably done a poor job explaining.  The hiccup occurs right BETWEEN the fully forward trigger location and the point at which the trigger sets (or "clicks" as you say) into the SA location.  If I continue to press the trigger past the rough spot, it does set in the SA location just like before.  No other problems with the trigger at all.  From the SA location on until it releases the striker, it is very smooth.

Though I didn't dunk the frame, I gave it a very good Q-tip cleaning (I was amazed how much residue I got off the trigger parts).  Unfortunately, the problem is still there.  After some more careful searching, I've found two other threads that seem to deal with the same problem:

http://www.gothammarketing.com/ikon....=1;t=43  -  (look at P99's reply about halfway down the page - I think this is exactly what I'm experiencing).

I was just thinking how nice and smooth the trigger had become after 500 rounds, then this suddenly came up right at the end of the class.  I think it's clean, and I'd never encountered this bump/catch/hiccup/rough-spot in the past.

At any rate, the pistol is still under warranty, so I'll probably send it back to S&W for them to take a look at.

Thanks everybody.

P88,

I'll check that out.  Before I send it in, I'll put a hundred rounds through it - who knows, maybe cycling it a bunch will clear it up.  I'll also give the frame a real bath.

Thanks.
