I went to the range on Saturday and during the course of our trip my gf was having continued issues with my Sig Mosquito. I rarely shoot the gun (it was bought for her to learn proper technique/get comfortable shooting a handgun with) and didn't think much of it bc the gun likes to fte if you limp wrist it, which she has a habit of doing. After the third fte I asked to take a look at it. The mag was not properly seated and that was causing the failure's. When I attempted to push the mag all the way in, I realized that the mag release button was stuck in the pushed in position, and it would not release to hold the mag in the proper position. I locked the gun up and figured that I would figure it out back at home.

 

When I got it home I put a drop of oil around the button to see if it would fix the problem. It didn't. I can manually pop the mag release back out if I do it from inside the mag well, but if I push the button in it sticks.

 

The gun has about ~800 rds through it and this has never happened before. It is not an issue of being clean or not, the gun is spotless.

 

Any suggestions on how to remedy the problem, or a smith in the Central Jersey area I can drop it off to to have it taken care of?

There's a tiny spring on the inside of the button that you won't see from the mag well, if I'm not mistaken. Message Bry@n He's a sig armorer.

I am sure it's just a case of something stuck in there. Maybe a spring issue also.

I looked as best I could, can't see anything stuck in there. It could be the mag release spring, but it almost feels like the mag release itself shifted and is now rubbing against the frame. Anyhow if you are familiar with these things let me know if I could drop it off to you and what the approx cost would be.

Your most likely missig the magazine catch/release spring or it's been broken or seized in place.

It should be pretty easy to remove check and repair. There itsnt really anything your gonna break getting to it.

As far as all the failure to feeds with this model most are due to the barrel ramp needed to be smoothed down.

The soft lead nose of the 22lr bullets catches the jump that most of the ramps have and they hang up. One really

easy way to tell if that's your issue is to check the round after a jam and see if it's been deted in a specific spot. They

look like fun little plikers but have been problem prone since their 1st release. There are a good number of reliability checkes

and fix's you can make on them. There are about 50 videos on youtube with them as well as complete disassembly. Why

pay a gun smith to swap a part when you can do it yourself.

This hasn't happened to me (yet, fingers crossed) but if you're afraid to take it apart, send it to Sig to have it looked at. I sent mine in to get looked at and had the gun back in a little over a week.

How did you make out?

How did you make out?

 

I watched the video you sent but haven't had the time to take the gun apart. Works been a little nuts. Hoping to take it apart on wed.

Throw it.

Throw it.

 

Do it...lol!

^ lol. This will be the next option.

Let us know how you make out.

First off thank you to Drew1 and those of you with advice.

 

I decided to take it apart tonight and I figured out what the issue was. The mag catch was rubbing the frame on the bottom of both sides and the actual release inside the mag well had accumulated some dirt/grit which pushed its way into the mag catch housing.

 

I cleaned the whole thing, and filed down the bottom portion of the mag release on both sides a little bit. I put it all back together and its functional again. I took it back apart to use a steel blueing pen on the area i filed and when thats set im going to oil it up to help it move easier.

 

Here are a couple pics of where it was rubbing and where the grit was.

 

 

Great! The hard part is working up the desire to take it apart yourself. Now you know what the components are, how it comes apart, and how to put it back together. You're on your way to becoming a Sig armorer!

Good for you Blake.

 

I figured it was something along those lines.

Yea thankfully it was actually very easy to dis and reassemble. I honestly hadn't taken it apart other than field stripping it for cleaning before this. I am glad she is back up and running!
