Mag catch question on new 2011

[zdog]

My new STI-2011 in 40cal arrived recently and I have a question about magazine insertion and the mag catch.

When I slam in a loaded magazine in the mag catch extends a little during the insertion as normal but there is a slight delay when it resets and a nasty irritating snapping sound when it finally resets. If I gently seat the magazine the catch does not do this. Sometimes it will not reset all the way and will remain extended about a 1/16 of an inch. My thought is that the mag is being over inserted and the release is not catching till the mag drops down a little. This is not a good thing when you need to slam a mag home during a match.

Second question. If I pull the trigger and hold the trigger down while the slide cycles and then release the trigger and allow it to reset the reset feels very sluggish. It is almost like the trigger would not reset if you would very slowly release it. I'm a 1911 guy and know that the reset is not entirely without a little resistantance but this pistol seems excessive in that regard. My guess the sear spring does not have enough tension because they used it to lighten the trigger down to 3.25 lbs.

Anyhow I am open to suggestions and thoughts. I would like to have an idea what I am talking about before I talk to the folks that made this Pistol.

Unless you have a few thousand rounds on this gun already, I think you may be being a bit over critical. If it's nearly new - I wouldn't get too concerned with how smooth it is, or isn't.

Now, for an about face of what I just said...

If it were mine, and bearing in mind that I'm at least as OC as you are and probably worse.... I'd detail strip it, inspect the parts you think are suspect and how well they fit in the gun (including the slide disco track and disco in frame bore) - deburr those parts as you see fit - clean, lube, reassemble and test fire a few hundred through it.

As far as the mag and mag catch go, cut the notch in the mag lower (only remove some on the bottom edge). This way there won't be anything for the catch to rest on if the mag is overinserted.

Thanks for the thought Steve. I understand what you are saying but I have never had to adjust a mag to fit the gun. I will keep this in mind it if comes to that.

.0001" is as small as you go? Piker.

3.25 pound trigger isn't very light, as competition guns go.

I have thought about my post on this subject. The spring weight on trigger take up is about right. I guess that means that they didn't cheat and just use sear spring tension as a means to reduce trigger pull to 3.25lbs. I will make another guess here and speculate that the ignition comonents were probably not stoned but rather just installed as recieved from the manufacturer. Maybe Creeper was right in that I need to put a couple of thousand rounds throught this thing before becoming too expectant.

One thing you'll discover about magazines is that they are all not created equal. Check them all against each other if some work well and others have the problem you mentioned previously.

These are supposed to prevent over insertion of mags.

Thanks,

These are currently out of stock. I ordered one anyhow. Dawson is good about returns if the item doesn't work as advertised. Anyone ever try one of these btw?

I have one in my Edge, I've only had it 9 months and no issues. It came in my CRP Edge from Dawson, so I have no point of reference of how it would be without one.

I have 3 of them and they work fine. A friend was using my Edge, and broke the ejector, which is why I installed the Posi-Lock. No issues since I made the change. I also have a Tactical 4.15 that I traded for, and it had a broken ejector and I swapped that out as well and haven't had any issues. The 3rd 2011, I installed it from the get go, and haven't had any issues.

Doubt it's a mag issue. The factory mag release sometimes need the hole the spring and screw sit in polished, and slicked up a little bit. also try moving the release back in forth in the grip with out any springs installed, bet its tight and dragging. Regularly use will loosen things up.

On the trigger, same deal - trigger bow is dragging on the grip, will work itself in with time or you can take it apart and polish the plastic up. Make sure you have enough return spring set on the mainspring.

Maybe some lube will help? Just a drop and keep at working on it...

Dawson sells a mag catch which supposedly helps prevent the exact problem you're talking about. As for the trigger, it isn't too light because my 2.25 lb trigger has a substantial reset. My best advice would be to take it to a competent gunsmith for him to look at.

I found the cause of the problems on my STI that I asked about and thought folks might want to know what the problem was.

1. Mag catch allowing over insertion of the magazine. I found that even when not really slamming the magazine home with the slide closed and rounds in the magazine that the mag catch was allowing over insertion and when the magazine finally dropped back a little after it hit the slide the mag catch would finally close.

The solution was installing a Dawson posi-lock mag release. This mag released fixed the problem as easy as removing the STI and installing the Dawson model. Good Job Dawson.

2. Trigger reset feels mushy almost like it would not reset if you took your finger off the trigger slowly.

The solution was:

I finally removed the slide and when I pressed down on the dis-connector the dis-connector would go down but not come up again unless I jiggled the trigger. It was as if it were sticking. I removed the ignition components and checked things out. I could reverse the disconnector and insert it from the top of the frame and there was no rubbing or resistance. I checked the sear spring and someone had buffed the portion of the sear spring that rides on the bottom of the disconnector. I got my loop out and looked at the engagement surface of the disconnector and could see that it had never been stoned. It took five minutes and two different stones to put a mirror finish on the part of the disconnector that rides on the sear spring and I was back in business.

This STI was a custom build from a name brand builder. I have another 5 items that need fixed aside from those listed above. I get the impression this gun was just assembled and not fitted. I am not happy.
